title: Stentless laparoscopic pyeloplasty: A single center experience.
abstract: OBJECTIVE
  To assess the effectiveness of laparoscopic stentless pyeloplasty for congenital ureteropelvic junction obstruction.
  
  
  METHODS
  This was a prospective comparative study conducted over a period of 5 years. The study included 35 cases of primary ureteropelvic junction obstruction (UPJO) with mean age of 29.5 years, divided in two groups- Group A (stent-less, 18 patients) and Group B (stented, 17 patients). Follow up ranged from one to 4years (mean 2 years). Transperitoneal laparoscopic Anderson- Hyene's pyeloplasty was standard for both the groups. Perioperative and postoperative complications were prospectively collected and analyzed by Statistical Package for Social Sciences (SPSS) 17 version using Pearson chi square test.
  
  
  RESULTS
  Both the groups were comparable with respect to preoperative differential renal function (DRF) and time required for maximum activity in minutes (tmax.min). Average post operative DRF was significantly higher than preoperative DRF in both the groups. Average tmax was significantly lower after pyeloplasty than pre operative tmax. Mean operative time, mean duration of urethral catheter, and mean duration of drain removal were comparable in both the groups. However bothersome irritative lower urinary tract symptoms (LUTS) and hematuria were significantly more in group B patients (P < 0.0001 and <0.013 respectively).
  
  
  CONCLUSIONS
  In experienced hands, laparoscopic stentless pyeloplasty is as effective method for treating UPJO as its stented counterpart. It is cost effective, avoids stent-related morbidity, and could be performed without compromising the success rate. However, more randomized studies are needed to evaluate the safety of stentless pyeloplasty.
