RESUMEN
To assess the effectiveness of laparoscopic stentless pyeloplasty for congenital ureteropelvic junction obstruction. 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 2[.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. Both the groups were comparable with respect to preoperative differential renal function [DRF] and time required for maximum activity in minutes [t[max].min]. Average post operative DRF was significantly higher than preoperative DRF in both the groups. Average t[max] was significantly lower after pyeloplasty than pre operative t[max]. 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]. 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
