Abstract Introduction To analyse the results achieved to treat iliac or pelvic ureteric stricture using laparoscopic reimplantation of the ureter in a psoic bladder. Material and method In a four-year period, we performed laparoscopic ureteral reimplantation in a psoic bladder in 6 patients (right/left 1:1; male/female 1:2; mean age 59.2 years, range 47-87). In 4 cases the lesion was iatrogenic and in 2 cases idiopathic. Ureteral resection with bladder cuff and cystorraphy followed by ipsilateral lymph node dissection was performed in idiopathic cases or those with history of previous urothelial tumour (4 cases in total) before ureteral reimplantation. Bladder was extensively mobilized and fixed to minor psoas tendon before performing ureteroneocystostomy. Mixed intra and extravesical technique with submucosal tunnel (Politano) was used in a case and in the remaining 5 cases extravesical technique with submucosal tunnel (Goodwin) was used. Mean follow-up was 26 months (range 18–34). Results There was no need to convert to open surgery. Time of surgery was 230 minutes in the case treated with Politano ureteroneocystostomy and 120 (range 75–150) in those treated purely extravesically. The mean hospital stay was 3.2 days (range 2–5). There were no intra or postoperative complications. Histologic assessment always revealed ureteral fibrosis and in 2 cases accompanying granulomatous inflammation and dysplasia. No patient suffered re-stricture or impairment in renal function during follow-up. Conclusions Laparoscopic ureteral reimplantation is an effective and safe minimally invasive technique to treat benign distal stricture of the ureter. Simplicity of extravesical reimplantation has an advantage over its intravesical counterpart.
