METHODS: Urology residents and specialists were invited to test the training model. They were asked to complete a pre-task questionnaire, to perform piecemeal and en bloc resection of 'bladder tumours' within the training model, and to complete a post-task questionnaire afterwards. Their performances were assessed by faculty members of the AUSTEG. For the face validity, a pre-task questionnaire consisting of six statements on TURBT and the training model were set. For the content validity, a post-task questionnaire consisting of 14 items on the details of the training model were set. For the construct validity, a Global Rating Scale was used to assess the participants' performances. The participants were stratified into two groups (junior surgeons and senior surgeons groups) according to their duration of urology training.
RESULTS: For the pre-task questionnaire, a mean score of ≥ 4.0 out of 5.0 was achieved in 5 out of 6 statements. For the post-task questionnaire, a mean score of ≥ 4.5 out of 5.0 was achieved in every item. For the Global Rating Scale, the senior surgeons group had higher scores than the junior surgeons group in 8 out of 11 items as well as the total score.
CONCLUSION: A porcine TURBT training model has been developed, and its face, content and construct validity has been established.
DESIGN: Excision of bladder endometriosis by first delineating the tumor via cystoscopy and simultaneously excising the nodule laparoscopically SETTING: Mahkota Medical Centre, Melaka, Malaysia.
INTERVENTION: Here we describe a simultaneous cystoscopic and laparoscopic excision of bladder endometriosis. The patient was first seen in 2005 at age 19 years with an endometrioma. She was single (virgo intacta) at that time. She underwent a laparoscopic cystectomy. Postoperatively, she received 3 doses of monthly gonadotropin-releasing hormone (GnRH) analogue injection. She was last seen in 2006 and was well. She conceived spontaneously after that and delivered 2 babies spontaneously in 2007 and 2010 in another city. She consulted me again in April 2016 complaining of dysuria, dysmenorrhea, and inability to hold her urine. She had consulted a urologist 6 months earlier. Cystoscopy performed by the urologist showed bladder endometriosis. No further surgery was performed, and she was given GnRH analogues for 6 months. However, her symptoms persisted after completion of the GnRH analogue. Examination and ultrasound showed a large bladder nodule measuring 4.17 × 2.80 cm. Intravenous urogram showed stricture in the upper right ureter. She underwent a combined urology and gynecology surgery to excise the bladder nodule. Informed consent was obtained from the patient, and the local institutional board provided the approval. The surgery was performed with the patient in the dorsosacral position. A Verres needle was inserted into the abdomen at the umbilicus, and carbon dioxide insufflation was performed. A 10-mm trocar was inserted in the umbilicus, and a 3-dimensional laparoscope (Aesculup-BBraun Einstein Vision; BBraun, Melsungen AG, Germany) was inserted to view the pelvis. Three 5-mm trocars were inserted, 1 on the right side and 2 on the left side of the abdomen. A RUMI (CooperSurgical, Trumbull, CT) uterine manipulator was placed into the uterine cavity. Laparoscopy showed no adhesions in the upper and mid-abdomen. The appendix and the intestines looked normal. Both the ovaries and fallopian tubes were normal. Uterine insufflation with methylene blue showed that both tubes were patent. There was dense endometriosis between the bladder and fundus of the uterus. The omentum was also adherent to the site of the endometriosis. There were endometriotic nodules on the left uterosacral ligaments and the peritoneum in the wall in the pouch of Douglas. The omentum was released, and laparoscopic adhesiolysis was performed. Both the paravesical spaces lateral to the nodule were dissected out. The bladder was released from the uterus with some difficulty. The peritoneal endometriosis in the Pouch of Douglas and the nodules in the left uterosacral ligament were excised. Cystoscopy was performed and stents were first placed in both ureters. The nodule was found to be in the central position, and the margins were about 2 cm from both the ureteral orifices. The nodule was seen protruding into the bladder containing bluish lesions. Demarcation of the bladder endometriosis was done using a resectoscope. Using a needle electrode, a deep circular incision was made around the bladder nodule and into the detrusor muscle. Cystoscopic perforation of the bladder was done and was seen laparoscopically. The bladder endometriotic nodule was completely excised laparoscopically after the demarcation line created via the cystoscopy. Stay sutures were first placed at the superior and inferior edges of the defect. The bladder was repaired continuously in 1 layer using polyglactin 3-0 sutures. The nodule was placed in a bag cut into smaller pieces and removed through the umbilical incision. At the end of the surgery a cystoscopy was perform to check the integrity of the suture. The pelvis was then washed. A bladder catheter was placed. The trocars were then removed under vision, and the rectus sheath was closed using polyglactin 1 suture. The skin incisions were closed. The operation time was 2 hours. The patient received antibiotics for 10 days. She was discharged with a catheter in place on day 3. She underwent a cystogram on day 10 of the surgery, and the bladder was found to be intact. The catheter was then removed. She was seen 6 weeks after the surgery and was well without any symptoms. The ureteric catheters were removed. Histopathology confirmed bladder endometriosis. Five months later she conceived spontaneously and delivered her third child naturally in June 2017. She was seen after her delivery and was advised to take oral contraceptive pills continuously or an intrauterine contraceptive device to prevent recurrence of the endometriosis. She took the oral contraceptive pills for 3 months and then refused any further treatment. She was last seen in February 2019 and was well without any symptoms.
CONCLUSION: In bladder endometriosis a combined approach with the urologist can assist in safely excising deep bladder endometriosis without removal of normal bladder tissue. Stents placed in the ureter assist in avoiding injury to the ureters. Demarcating the endometriotic nodule by the urologist through the bladder and excising the bladder nodule laparoscopically is both safe and effective.
PATIENTS AND METHODS: A systematic search was conducted according to the PRISMA guidelines for studies reporting on outcomes after TMT and RC. A total of 57 studies including 30,293 patients were included. The 10-year overall survival (OS), disease-specific survival (DSS), and recurrence-free survival (RFS) rates for TMT and RC were assessed.
RESULTS: The mean 10-year OS was 30.9% for TMT and 35.1% for RC (P = 0.32). The mean 10-year DSS was 50.9% for TMT and 57.8% for RC (P = 0.26). NAC was administered before therapy to 453 (13.3%) of 3,402 patients treated with TMT and 812 (3.0%) of 27,867 patients treated with RC (P<0.001). Complete response (CR) was achieved in 1,545 (75.3%) of 2,051 evaluable patients treated with TMT. A 5-year OS, DSS, and RFS after CR were 66.9%, 78.3%, and 52.5%, respectively. Downstaging after transurethral bladder tumor resection or NAC to stage ≤pT1 at RC was reported in 2,416 (29.1%) of 8,311 patients. NAC significantly increased the rate of pT0 from 20.2% to 34.3% (P = 0.007) in cT2 and from 3.8% to 23.9% (P<0.001) in cT3-4. A 5-year OS, DSS, and RFS in downstaged patients (≤pT1) at RC were 75.7%, 88.3%, and 75.8%, respectively.
CONCLUSION: In this analysis, the survival outcomes of patients after TMT and RC for MIBC were comparable. Patients who experienced downstaging after NAC and RC exhibited improved survival compared to patients treated with RC only. Best survival outcomes after TMT are associated with CR to this approach.
MATERIALS AND METHODS: A systematic online search was conducted according to PRISMA statement for publications reporting on UR after RC. From initial 802 results, 14 articles including 6169 patients were included finally after exclusion of ineligible studies.
RESULTS: The incidence rate of UR was 4.4% (1.3%-13.7%). It was significantly lower with neobladder diversion (odds ratio = 0.44, 95% CI: 0.24-0.79, P = 0.006). Muscle invasion (hazard ratio = 1.18, 95% CI: 0.86-1.62, P = 0.31), carcinoma in situ (hazard ratio 0.97, 95% CI: 0.64-1.47, P = 0.88), prostatic stromal involvement (hazard ratio = 2.26, 95% CI: 0.01-627.75, P = 0.78), and prostatic urethral involvement (hazard ratio = 2.04, 95% CI: 0.20-20.80, P = 0.55) have no significant effect on UR. Men displayed tendency toward higher incidence of UR (odds ratio = 2.21, 95% CI: 0.96-5.06, P = 0.06). Absence of recurrence displayed tendency toward better disease specific survival, yet not significant (hazard ratio = 0.84, 95% CI: 0.66-1.08, P = 0.17). These results are limited by the retrospective nature of the included studies.
CONCLUSION: Muscle invasion, carcinoma in situ and prostatic stromal or urethral involvement at time of RC have no significant effect on UR. Orthotopic neobladder is associated with a significant lower risk of UR after RC.
MATERIAL AND METHODS: A total of 320 consecutive patients staged with cM0 bladder cancer underwent radical cystectomy (RC) between 2004 and 2013. The presence of TAIC (either located peritumorally [PIC] and/or intratumorally [IIC]) on histological slides was retrospectively assessed and correlated with outcomes. Kaplan-Meier analyses were used to estimate the impact of TAIC on recurrence-free (RFS), cancer-specific (CSS), and overall survival (OS). Multivariable Cox-regression analysis was carried out to evaluate risk factors of recurrence. The median follow-up was 37 months (IQR: 10-55).
RESULTS: Of the 320 patients, 42 (13.1%) exhibited IIC, 141 (44.1%) PIC and 137 (42.8%) no TAIC in the cystectomy specimens. Absence of TAIC was associated with higher ECOG performance status (P = 0.042), histologically advanced tumor stage (≥pT3a; P < 0.001), lymph node tumor involvement (pN+; P = 0.022), positive soft tissue surgical margins (P = 0.006), lymphovascular invasion (P < 0.001), and elevated serum C-reactive protein levels (P < 0.001). The rate of never smokers was significantly higher in the IIC-group (64.3%) compared to the PIC-group (39.7%, P = 0.007) and those without TAIC (35.8%, P = 0.001). The 3-year RFS/CSS/OS was 73.9%/88.5%/76.7% for patients with IIC, 69.4%/85.2%/70.1% for PIC and 47.6%/68.5%/56.1% for patients without TAIC (P < 0.001/<0.001/0.001 for TAIC vs. no TAIC). In multivariable analysis, adjusted for all significant parameters of univariable analysis, histologically advanced tumor stage (P = 0.003), node-positive disease (P = 0.002), and the absence of TAIC (P = 0.035) were independent prognosticators for recurrence.
CONCLUSIONS: In this analysis, the presence and location of TAIC in cystectomy specimens was a strong prognosticator for RFS after RC. This finding suggests that the capability of immune cells to migrate into the tumor at the time of RC is prognostically important in invasive bladder cancer.
MATERIALS AND METHODS: An online search was done for studies reporting incidental prostate cancer in cystoprostatectomy specimens. After following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines we identified a total of 34 reports containing 13,140 patients who underwent radical cystoprostatectomy for bladder cancer with no previous history of prostate cancer. A cumulative analysis was performed on the available data regarding prevalence, clinicopathological features and oncologic outcomes. RevMan, version 5.3 was used for data meta-analysis.
RESULTS: Of the 13,140 patients incidental prostate cancer was detected in 3,335 (24.4%). Incidental prostate cancer was significantly associated with greater age (Z = 3.81, p = 0.0001, d = 0.27, 95% CI -0.14-0.68), lymphovascular invasion of bladder cancer (Z = 2.07, p = 0.04, r = 0.14, 95% CI 0.09-0.18) and lower 5-year overall survival (Z = 2.2, p = 0.03). Among patients with clinically significant and insignificant prostate cancer those with clinically significant prostate cancer significantly more frequently showed a positive finding on digital rectal examination (Z = 3.12, p = 0.002, r = 0.10, 95% CI 0-0.19) and lower 5-year overall survival (Z = 2.49, p = 0.01) whereas no effect of age was observed (p = 0.15). Of 1,320 patients monitored for biochemical recurrence prostate specific antigen recurrence, defined as prostate specific antigen greater than 0.02 ng/ml, developed in 25 (1.9%) at between 3 and 102 months.
CONCLUSIONS: This meta-analysis suggests that incidental prostate cancer detected during histopathological examination of radical cystoprostatectomy specimens might be linked with adverse characteristics and outcomes in patients with invasive bladder cancer.
METHODS: A total of 131 consecutive patients exhibiting NMIBC at primary diagnosis were retrospectively investigated whether they had undergone any HAL-guided TURBT prior to RC. Uni- and multivariable analyses were used to evaluate the impact of HAL-TURBT on cancer-specific (CSS) and overall survival (OS). The median follow-up was 38 months (IQR 13-56).
RESULTS: Of the 131 patients, 69 (52.7%) were managed with HAL- and 62 (47.3%) with white light (WL)-TURBT only prior to RC. HAL-TURBT was associated with a higher number of TURBTs prior to RC (p = 0.002) and administration of intravesical chemotherapy (p = 0.043). A trend towards a higher rate of tumor-associated immune cell infiltrates in RC specimens (p = 0.07) and a lower utilization rate of post-operative systemic chemotherapy (p = 0.10) was noted for patients who were treated with HAL-TURBT. The 5-year CSS/OS was 90.9%/74.5% for the HAL-group and 73.8%/55.8% for the WL-group (p = 0.042/0.038). In multivariable analysis, lymph node tumor involvement (p = 0.007), positive surgical margins (p = 0.001) and performance of WL-TURBT only (p = 0.040) were independent predictors for cancer-specific death.
CONCLUSIONS: The present data suggest that the resection of NMIBC under HAL exerts a beneficial impact on outcomes of patients who will need to undergo RC during their course of disease. This finding may be due to improved risk stratification as the resection under HAL may allow more patients to be treated timely and adequately.
