Laparoendoscopic single site reconstructive procedures in urology: Medium term results

摘要

Purpose: Despite numerous retrospective series of laparoendoscopic single site surgery, cohorts have generally been small and followup largely short-term. Therefore, we report intermediate term outcomes for patients undergoing reconstructive laparoendoscopic single site procedures at a single institution. Materials and Methods: Upon review of our prospectively maintained laparoendoscopic single site urological database of 185 cases, 32 reconstructive procedures were identified including pyeloplasty (25), ileal interposition (3), ureteroneocystostomy (3) and retrocaval ureter repair (1). Perioperative data were reviewed, and clinical and radiographic success was noted. Results: Median followup was 24.4 months for pyeloplasty, 35 months for ileal interposition, 29.4 months for ureteroneocystostomy and 20 months for retrocaval ureter repair. At last followup 24 of 25 patients treated with pyeloplasty, 2 of 3 with ileal ureter, 3 of 3 with ureteroneocystostomy and 1 of 1 with retrocaval ureter reported being asymptomatic or improved after the procedure. Delayed incisional hernia repair was required in 1 patient. One death occurred during the followup period, remote from the date of surgery. No other complications were noted. Conclusions: Intermediate term results after laparoendoscopic single site reconstructive procedures remain promising. Further followup of this patient population is required to ensure the durability of results. Prospective evaluation is also needed to assess if advantages exist for laparoendoscopic single site reconstructive procedures compared to standard minimally invasive approaches.
