Pure natural orifice translumenal endoscopic surgery management of simple XXXX : 2-year follow-up results.

@entity1 @entity8 @entity5 @entity158
BACKGROUND AND PURPOSE: Retrograde ureteroscopic marsupialization is a pure natural orifice translumenal endoscopic surgery (NOTES). We retrospectively examined the feasibility and safety of this technique to manage symptomatic simple @entity8 . @entity1 AND METHODS: Sixteen @entity1 with simple @entity8 were selected and treated by incising the cyst wall to drain into the collecting system through retrograde ureteroscopy. A retrospective observational study was performed to evaluate the @entity1 's symptomatic and radiologic results after ureteroscopic marsupialization. Symptomatic success based on @entity158 relief was evaluated using a visual analog @entity158 scale preoperatively and postoperatively. Radiologic success was defined as no recurrence of the cyst or a reduction in cyst size by at least half. RESULTS: There were no intraoperative or postoperative complications observed. The mean operative time was 35 minutes (range 20-50 min). The mean hospital stay was 3.4 days (range 2-5 d). Of the 16 @entity1 , one @entity1 was lost at follow-up. The symptoms based on @entity158 had resolved in 13 (83%) cases but remained in 2 cases at a mean follow-up of 24.2 months (range 6-36 mos). The average visual analog @entity158 scale decreased from 6.7 (range 4-9) to 1.1 (range 0-5) at the sixth month. The mean size of all cysts decreased from 6.8 cm (range 4-10 cm) to 1.3 cm (range 0-5 cm). Radiographic success was achieved in 93% (14/15) of @entity1 . Cytology and cyst wall pathology reports revealed no evidence of @entity5 . CONCLUSIONS: Retrograde ureteroscopic marsupialization is a complete transurethral NOTES marsupialization. With appropriate @entity1 selection, the minimally invasive retrograde ureteroscopic marsupialization is feasible, safe, and effective. It can be preferred to more invasive laparoscopic or open surgical approaches.
