Fulltext Percutaneous renal surgery for urolithiasis

Tan HM, Cheung HS

Med J Malaysia, 1990 Jun;45(2):118-22.
PMID: 2152015

Sixty eight consecutive cases of percutaneous renal surgery, percutaneous nephrolithotripsy (PCNL), were performed on 64 patients (male-41, female-23) at the Subang Jaya Medical Centre from April 1988 to July 1989. All the cases were done as a one stage procedure. Fifty eight stones were large renal or staghorn and ten were ureteric. Thirty cases (41%) were stone free after PCNL alone. Thirty eight cases had residual fragments needing extracorporeal shockwave lithotripsy (ESWL). Mean operating time was 109.6 +/- 36.0 minutes. Mean hospital stay was 4.5 +/- 1.8 days. At three months follow-up, 86% of the cases were stone free. The remaining had residual sand (less than 3mm). Minor complications occurred in six patients. None required major surgical intervention post PCNL.

Comparison of the Efficacy and Safety of Laparoendoscopic Single-Site Surgery with Conventional Laparoscopic Surgery for Upper Ureter or Renal Pelvis Stones in a Single Institution: A Randomized Controlled Study

PURPOSE: To evaluate the utility and safety of laparoendoscopic single-site surgery (LESS) in comparison with conventional laparoscopic (CL) surgery for the treatment of upper urinary tract stones.
MATERIAL AND METHODS: Between June 2011 and May 2012, 20 patients with upper urinary tract stones were included in this prospective randomized study. The patients were assigned into the LESS group or CL group in a one-on-one manner using a random table. The clinical parameters were evaluated in the immediate postoperative period, and the stone clearance rate was evaluated via non-contrast computer tomography at one month postoperatively.
RESULTS: There were no significant differences in patient demographics or preoperative stone sizes between the two groups. The perioperative parameters, including operative time, estimated blood loss, postoperative pain scores, length of hospital stay, and changes in renal function, were comparable. No transfusions or open conversions were required in either group. The incidence of residual stones was lower in the LESS group (1 case) than in the CL group (2 cases). However, this difference was not statistically significant.
CONCLUSIONS: For large and impacted upper ureteral stones, the effectiveness and safety of LESS were equivalent to those of CL. Further randomized control trials with larger sample sizes are needed to strengthen the conclusions of this study.&nbsp.

This is a retrospective review of 200 day-care ureteroscopies performed between April 1998 and October 2002. The aim was to determine the feasibility and safety of this procedure. The mean age was 38.8 years and 75% of them were male. Eighty-three percent were ASA 1 and the remainders were ASA 2. The side of procedure were 48.5% right, 2.5% left and 6% both sides. Fentanyl and proprofol were used during induction. Calculi were found in 82.5% of cases. Rigid and flexible scope were used in 91.5% and 10.5% of cases. There were 33% upper, 23% mid and 44% distal ureteric stones. The mean stone size was 9.37 X 6.93mm. Seventy-four percent required a ureteric stent insertion. The mean operative time was 58.3 minutes. Four percent of patients experienced pain post-operatively relieved by NSAID injection. Repeat ureteroscopy performed in 30% of patients. There were zero admission rates. This study suggests day-care ureteroscopy is effective, safe and well tolerated by patients.

Fulltext Pneumatic ureterolithotripsy in paediatric and adolescent patients: a ten-year experience at the Hospital Universiti Sains Malaysia

Two to three percent of stone disease cases occur in the paediatric age group. It is common in some parts of the world, such as in Turkey, India and Thailand. More than 50 percent of stones in children are still managed through open surgery. Ureteroscopic intervention for children remains a challenging treatment option. However, in contemporary urology practice, this mode of intervention is becoming more common. In this retrospective study, we reviewed our experiences with ureteroscopy and pneumatic lithotripsy in the paediatric and adolescent age group.
