PMID: 267467

Eight cases of xanthogranulomatous pyelonephritis occurring in an oriental population are reported. The patients were mostly middle-aged, and there was a female preponderence. Nephrectomy controlled the disease in all cases. Diagnosis on clinical and radiological grounds is difficult, and it is often only made on pathological examination of the kidney after nephrectomy. The nature of the disease remains obscure.

Wilms tumour with poor response to pre-operative chemotherapy: A report of 2 cases

Tan HCL, Tan JH, Vellusamy VM, Vasavan Y, Lim CS

Malays J Pathol, 2020 Aug;42(2):267-271.

PMID: 32860380

INTRODUCTION: Majority of Wilms tumour (WT) responds well to pre-operative chemotherapy. In Malaysia, incidence of WT is rare with only two cases reported per one million populations yearly. This case report is to highlight on the awareness of WT in an Asian population and highlight two cases and challenges faced after pre-operative chemotherapy.

CASE REPORT: In this case series, we report on two cases of WT which had poor response to pre-operative chemotherapy. Both cases underwent surgery after pre-operative chemotherapy and recovery was uneventful during a two-year follow-up.

DISCUSSION: Both patients had chemotherapy prior planned surgery, but had unfortunate poor tumour response. The tumour progressed in size which required a radical nephrectomy. The histology report for the first case had more than 60% blastemal cells remaining despite giving pre-operative chemotherapy with no focal anaplasia. This showed poor response to chemotherapy evidenced by the high number of blastemal cells. The second case was a stromal type WT which is known for poor response and may lead to enhancement of growth and maturation induced by chemotherapy. These were the possible reason of poor response of WT in these two cases.

Transperitoneal laparoscopic nephrectomy for renal tumour disease versus non-tumour disease: What are the differences in outcomes?

Khai YT, Teck MT

Med J Malaysia, 2020 05;75(3):240-245.

PMID: 32467539

INTRODUCTION: Laparoscopic nephrectomy is the standard of care for the removal of both non-functioning and tumourbearing kidneys. This study was conducted to compare the characteristics and outcomes follow-ing laparoscopic transperitoneal nephrectomy (TP) for tumour and nontumour disease.

METHODS: We retro-spectively reviewed all TP nephrectomies performed in the Hospital Sultanah Bahiyah Alor Setar, Kedah between January 2016 and July 2017.

RESULTS: A total of 36 eligible cases were identified, 10 of which were for renal tumours and the others for nonfunctioning kidneys. There were no statistically significant differ-ences between the two groups in terms of demographics and comorbidities. We also did not identify any sta-tistically significant differences between the two groups in terms of operating time, blood loss, need for transfusion, septic complications and postoperative recovery. The only significant difference between the groups was the postoperative rise in serum creatinine, which was higher in the tumour disease group (mean rise 23.4 vs 5.35µmol/l; p = 0.012).

CONCLUSIONS: Our study showed that laparoscopic nephrectomy is both feasible and safe for the treatment of tumour and non-tumour renal disease with low complication rates in both groups.

Fulltext The value of pre-operative embolisation in primary inferior vena cava paraganglioma

Zaki FM, Osman SS, Abdul Manaf Z, Mahadevan J, Yahya M

Malays J Med Sci, 2011 Apr;18(2):70-3.

PMID: 22135590

We report a case of a 13-year-old boy who complained of progressive abdominal distension and symptoms of anaemia. Radiological investigations revealed that the child had a hypervascular tumour of the inferior vena cava (IVC). Unfortunately, the child presented with acute lower gastrointestinal bleed soon after the investigation. He underwent an urgent pre-operative embolisation, aimed to reduce the tumour vascularity. A total resection of the tumour, right nephrectomy, and partial duodenal resection were done within 24 hours post-embolisation. The child was stable postoperatively. The histopathological examination revealed chromogranin-positive paraganglioma originating from the IVC. We highlight the radiological findings of rare primary IVC paraganglioma and the role of embolisation prior to surgical removal of the tumour.

J Coll Physicians Surg Pak, 2014 Mar;24 Suppl 1:S68-70.

PMID: 24718014 DOI: 03.2014/JCPSP.S68S70

Superior vena caval syndrome (SVCS) is a debilitating condition attributed to malignancy in more than 70% of cases. However, solitary head and neck metastases arising from renal cell carcinomas without evidence of disease elsewhere are rare. We report a case of renal cell carcinoma presenting as a rapidly growing right cervical lymph node with compression on the subclavian vein causing superior vena caval syndrome (SVCS). There was pulmonary embolism as well. Biopsy of the neck mass confirmed metastatic clear cell carcinoma with primary found in the (L) kidney. The patient had partial response to focussed radiotherapy to neck mass and Sunitinib (tyrosine kinase inhibitor) before succumbing to the disease.

PMID: 7565195

Malignant fibrous histiocytoma is a mesenchymal tumour which can involve the genitourinary organs primarily or by secondary extension. Both conditions are rare. We report four cases of retroperitoneal malignant fibrous histiocytoma involving the kidney by local extension. Diagnosis was difficult because of diverse, non-specific clinical features and may only be reached at operation or post mortem. Prognosis is poor. Although en bloc tumour resection with nephrectomy was possible in two patients, they returned with recurrences.

Renal cell carcinoma (RCC) has been shown to cause venous migration in the inferior vena cava (IVC). It is very important for preoperative imaging to be carried out, which will decide the surgical approach for the patient. Duplication of IVC is an uncommon anomaly. We report a case of RCC with duplication of IVC.

Fulltext Renal cell carcinoma in a von Hippel-Lindau syndrome: when should phaeochromocytoma be anticipated?

Azarisman SM, Nor Azmi K

Singapore Med J, 2007 Aug;48(8):779-82.

PMID: 17657389

A 39-year-old man was diagnosed with von Hippel-Lindau syndrome, which was associated with retinal haemangioblastoma, cervical cord haemangioblastoma and bilateral renal cell carcinoma. He subsequently underwent an arterial embolisation and cervical laminectomy, following a spinal angiogram of the cervical lesion. He also had a right radical nephrectomy, with no perioperative complications. However, on admission for the left radical nephrectomy, he was noted to have preoperative hypertension. Further investigation revealed an enlarged left adrenal gland on abdominal computed tomography scan and raised urinary catecholamines. We discuss the risk of renal cell carcinoma and phaeochromocytoma arising concomitantly in von Hippel-Lindau syndrome, and how best to investigate and manage them.

Post renal transplant Castleman's disease resolved after graft nephrectomy: a case report

Al Otaibi T, Al Sagheir A, Ludwin D, Meyer R

Transplant Proc, 2007 May;39(4):1276-7.

PMID: 17524952

Angiofollicular lymphoid hyperplasia (Castleman's disease) is a lymphoproliferative process thought to be mediated by overexpression of II interleukin-6. Castleman's disease has two variants: Castleman's disease has two variants: Hyaline vascular type and plasma cell variant (multicentric Castleman's disease). The hyaline vascular type tends to be localized, and the plasma cell variant shows more systematic signs and carriers a worse clinical prognosis. Castleman's disease is associated with B-cell lymphoma, Kaposi sarcoma, Human herpes virus 8 (HHV-8), and Epstein-Barr virus. Castleman's disease have been described thrice post kidney transplant. In this report, we document the course of a renal recipient who developed the plasma cell variant of Castleman's disease at 16 months after failure of his allograft and return to dialysis. He displayed clinical resolution of this complication after graft nephrectomy. To our knowledge, this is the first case where the disease manifestations disappeared after graft removal. Our patient experienced chronic renal allograft rejection which may have driven all the systematic manifestations of multicentric castleman's disease and possibly reactivated a latent HHV-8 infection. In this case immunohistochemical testing for HHV-8 was not available to prove a role for this agent.

NEPHRON-SPARING SURGERY IN PATIENTS WITH RENAL CELL CARCINOMA EXTENDING TO THE MAIN RENAL VEIN: INTRARENAL AND EXTRARENAL THROMBECTOMY

Shchukin D, Lisova G, Khareba G, Polyakov M, Antonyan I, Kopytsya M, et al.

PMID: 32011290

In most cases RCC with venous extension is an indication for radical nephrectomy. However, in patients with imperative indications for nephron-sparing surgery a kidney resection with thrombectomy in rare situations is possible. We present a surgical technique for nephron-sparing surgery in patients with tumor spreading into the main renal vein. From 2007 to 2019 seven partial nephrectomies with removal of the tumor thrombus from the main renal vein were performed. Absolute imperative indications were recorded in 6 (85.7%) patients (4 with solitary kidney, 2 with bilateral tumors). Dimensions of renal tumor averaged 6.5±2.3 cm. Intravenous part of the tumor penetrated the initial portion of the renal vein in 3 cases, main trunk of the renal vein in 3 cases, and cavarenal portion of the IVC in 1 case. The average length of the tumor thrombus was 24.0±6.9 mm, and the width was 9.3±4.8 mm. Tumor thrombi were classified as intrarenal and extrarenal. In accordance with this principle surgical procedures were divided into partial nephrectomy with intrarenal (3/42.9%) and extrarenal thrombectomy (4/57.1%). Intrarenal thrombectomy was characterized by thrombus removal out of the vein lumen from the side of the kidney resection area, while extrarenal thrombectomy included additional opening the lumen of the main renal vein or inferior vena cava (IVC). In one patient hypothermic perfusion of the kidney in situ was used. In two cases the extracorporeal partial nephrectomy with kidney autotransplantation was performed. Warm ischemia time averaged 14.0 minutes. The time of ischemia during hypothermic perfusion in situ reached 76 minutes, the time of cold ischemia during extracorporeal surgery averaged 68.0 minutes. The volume of blood loss did not exceed an average of 621.4±146.8 ml. Early postoperative complications occurred in 4 (57.1%) cases (bleeding -1, ischemic stroke -1, deterioration of renal failure -2). Postoperative mortality was registered in 1 patient due to bleeding and heart failure. The follow-up period averaged 28.7±18.9 months. Distant metastases occurred in 1 (14.3%) patient after 16 months. Local tumor recurrence in the remnant kidney after nephron-sparing surgery was not detected in any case. Nephron-sparing surgery may be used to treat patients with kidney tumors and neoplastic venous thrombosis. However, this complex surgical approach requires further technical improvement.

PMID: 22135565 MyJurnal

Metastatic renal cell carcinoma (RCC) presenting with multiple deposits in the head and neck region is unusual. It is not uncommon for a RCC to metastasise to a distant site after years of a tumour-free period, but most of it would be expected to have a single site of deposit. We report a rare case of a patient who had a nephrectomy 10 years earlier for RCC and presented with tumours in the frontal sinus and posterior pharyngeal wall. Radiological imaging and histology confirmed metastatic RCC at both sites.

Malaysian Journal of Psychiatry, 2018;27(1):0-0.

MyJurnal

In recent years, more cases of manic switches on Mirtazapine have been reported. In this report, we discuss a case of manic switch in a gentleman who was treated as unipolar depression. A 66-year-old man presented to psychiatry 8 months following a nephrectomy for symptoms of depression. Treatment with Sertraline 50mg daily was initiated and titrated to 150mg, along with Zolpidem and Clonazepam to aid his sleep. Despite these medications he never achieved remission and continued to have persistent anxiety and insomnia. Due to suboptimal control, treatment was changed to Mirtazapine 15mg daily. At day 20 he showed symptoms of mania which included talkativeness, increased goal directed activities, reduced need for sleep and socially disinhibited behavior. Mirtazapine was discontinued, and treatment was changed to Sodium Valproate, optimized to 1000mg daily, augmented with Quetiapine 150mg daily. Remission was achieved after 4 months and he has remained asymptomatic for 2 months. This was his first episode of mania, and a diagnosis of Bipolar I disorder was made. In conclusion, antidepressant induced manic switches are common, they are relatively under-appreciated and under-reported, especially with the use of sleep-promoting antidepressants. All antidepressants should be considered to be a potential mediator of a switch in view of its pharmacological properties.

Renal cell carcinoma (RCC) is the one of the most common type of of cancer of the kidneys affecting adults. A 35- year-old man, with Von Hippel Lindau (VHL) syndrome was referred for bilateral renal mass in a follow up CT for evaluation. Open partial left nephrectomy was performed and the final histopathological report confirmed the diagnosis. One of the most important genetic and hereditary risk factor for RCC is Von Hippel-Lindau syndrome (VHL). RCC in VHL may occur bilaterally in some cases, so preserving renal parenchymal function is a major therapeutic goal and nephron sparing surgery provides a favorable patient outcome.

With maturing functional and oncologic outcomes data, open partial nephrectomy (OPN) has become the standard of care for T1a renal tumor. Laparoscopic approach can provide a speedier recovery with less blood loss and postoperative pain. Presuming adequate laparoscopic expertise, laparoscopic partial nephrectomy can provide equivalent oncologic outcome as for OPN albeit with higher urologic complications rate and longer warm ischemia time. With refinement of technique and use of robotic assistant, the shortcomings of laparoscopic approach can be further reduced. This article is a mini-review on the current status of laparoscopic approach to partial nephrectomy in the management of small renal mass.

Laparoscopic retroperitoneal partial nephrectomy (LRPN) is a technically demanding kidney surgery due to the limited space and unfamiliar approach in the retroperitoneal space. The aim of this study is to review the outcome of our initial experience in performing this procedure. All patients who underwent LRPN between 2019 to 2022 were included in this retrospective review. A total of 23 patients underwent LRPN. The mean operating time was 178±43 minutes and mean warm ischemia time was 20±5 minutes. The average estimated blood lost was 89±68ml and the mean postoperative hospital stay was 3.6±0.8 days. Two patients (11.1%) had positive margin and no local recurrence was seen after mean follow up of 15.8±12.0 months. Our initial experience on LRPN showed promising results to perform partial nephrectomy safely and effectively.

PMID: 18935731

Hand-assisted laparoscopic nephrectomy (HAL-N) and nephroureterectomy (HAL-NU) were introduced to bridge the gap between open and laparoscopic surgery. This newer technique has the benefits of both laparoscopic and open surgical approaches but has a shorter learning curve and decreased operative time compared to laparoscopic surgery. A review of our 2-year experience showed that for the seventeen cases of HAL-N that was performed, the mean operative time was 187.8 minutes while the mean length of hospital stay was 4.1 days. For the two HAL-NU cases, the mean operative time was 415 minutes while the mean length of hospital stay was 5.5 days. Only one complication occurred and it was an incisional hernia at the hand-port site. There was no recurrence for the carcinoma cases. Our experience shows that this technique is feasible and safe.

Feasibility and safety of transvaginal specimen extraction for laparoscopic living donor nephrectomy: An Indonesian perspective compared with three different approaches

Hendri AZ, Soerohardjo I, Dewi KA, Danurdoro A

Med J Malaysia, 2023 May;78(3):270-278.

PMID: 37271835

INTRODUCTION: Laparoscopic live donor nephrectomy (LLDN) continues to expand in minimally invasive surgery; nevertheless, the studies are inadequate to compare standard kidney extraction with TV-NOSE in less-developed countries. This study compared TV-NOSE with conventional kidney specimen extractions.

OBJECTIVE: To examine the feasibility of TV-NOSE in live donor nephrectomy.

MATERIALS AND METHODS: 53 patients received LDN surgery at our hospital from September 2017 to December 2021. Retrospectively, living donor nephrectomy with TV-NOSE was compared to three different surgical procedures with standard specimen extraction.

RESULTS: 53 donor patients were included: 15 open (OLDN), 12 retroperitoneoscopic living donor nephrectomy (RPLDN), 10 transperitoneal living donor nephrectomy (TPLDN), and 16 standard laparoscopic living donor nephrectomy with transvaginal extraction (SLLDN TV-NOSE). SLLDN TVNOSE's longer operating time (p<0.0041) did not affect graft function. SLLDN TV-NOSE and RPLDN had shorter lengths of stay and better VAS trends than open LDN and TPLDN (p<0.05). SLLDN TV-NOSE donors reported acceptable surgical outcomes and unchanged sexual function. All patients had similar discharge creatinine levels, with 1-year transplant survival of 98% and just 1 graft loss in the TPLDN group.

CONCLUSION: SLLDN TV-NOSE is equivalent to RPLDN and better than open LDN and TPLDN in terms of duration of stay, VAS score, surgical outcomes, and sexual function. TVNOSE is a safe surgical procedure with an acceptable donor complication. TV-NOSE may be safely conducted in both developed and developing countries with proper patient selection.
