Background and Objectives:Renal cysts have a high prevalence in the general population, and their estimated incidence increases with age. Renal cyst aspiration (usually with sclerotherapy) or open/laparoscopic decortication is a generally effective and safe method in the treatment of symptomatic simple renal cysts. The success rates of laparoscopic decortication and percutaneous aspiration-sclerotherapy were compared to assist in the decision making for the procedure.Methods:A total of 184 patients with symptomatic simple renal cysts were treated with either laparoscopic decortication in 149 cases or percutaneous aspiration-sclerotherapy in 35 cases. The follow-up period was approximately 35 months, and the symptomatic and radiologic success rates of the 2 techniques were compared retrospectively.Results:Laparoscopic decortication was found to have high success rates, a low recurrence rate, and minimal morbidity. Percutaneous aspiration-sclerotherapy is an outpatient procedure with a minimally higher recurrence rate.Conclusion:When a symptomatic cyst is encountered and treatment of the cyst is indicated, laparoscopic decortication is a more efficient method that offers better results than percutaneous aspiration-sclerotherapy.

Objective. Retrograde intrarenal surgery (RIRS) performed using a flexible ureterorenoscope marked the beginning of a new era in urology. Today, even staghorn stones are successfully treated via RIRS. The recommended treatment for larger stones is percutaneous nephrolithotomy (PNL). However, the question of whether PNL or RIRS should be the first-line treatment option for larger stones remains controversial. In this study, we contribute to the debate by comparing the success and complication rates of PNL and RIRS that were used to treat renal pelvis stones 2-3 cm in diameter. Materials and Methods. The medical records of 154 patients (74 PNL, 80 RIRS) were retrospectively evaluated. PNL patients were placed in Group 1 and RIRS patients in Group 2. Results. The complete stone-free rates were 95.5% in the PNL group and 80.6% in the RIRS group 1 month postoperatively (P = 0.061). The respective complication rates (evaluated using the Clavien system) were 13.5% and 8.8% (P = 0.520). Conclusions. RIRS affords a comparable success rate, causes fewer complications than PNL, and seems to be a promising alternative to PNL when larger stones are to be treated. Prospective randomized controlled trials are needed to confirm these findings.

The aim of the study was to compare percutaneous nephrolithotomy (PCNL) and staged retrograde flexible ureteroscopy (FURS) methods used in the treatment of kidney stones of 2 cm or more in diameter. The study comprised a total of 60 patients with a diagnosis of kidney pelvic stones more than 2 cm in diameter, for whom surgery was planned between January 2013 and January 2014. The patients were randomly allocated to two groups as staged retrograde FURS (Group A) and PCNL (Group B). Comparison of the groups was made with respect to operating time, number of procedures, total treatment time, length of hospital stay, stone-free rates and complications according to the Clavien-Dindo classification. In Group A, the total operating time of multiple sessions was 114.46 min. In Group B, a single session of PCNL was applied to all patients and the mean operating time was 86.8 min (p = 0.014). Mean total treatment time was 2.01 weeks in Group A and 1 week in Group B (p < 0.01). The mean total hospitalization time was 3.66 days in Group A and 3.13 days in Group B (p = 0.037). At the end of the sessions, clinically insignificant residual fragments were observed in ten patients of Group A and one patient of Group B (p = 0.03). No statistically significant difference was determined between the groups in terms of stone-free rates or complications. Although current technology with FURS is effective on large kidney stones, it has no superiority to PCNL due to the need for multiple sessions and long treatment time.
