title: Bladder psoas hitch in hydronephrosis due to pelvic endometriosis: outcome of urodynamic parameters.
abstract: OBJECTIVE
  To evaluate modifications in bladder sensitivity and function after ureteroneocystostomy with bladder psoas hitch for hydronephrosis due to deep pelvic endometriosis.
  
  
  METHODS
  Prospective study.
  
  
  METHODS
  Center for the Treatment of Endometriosis of the Department of Obstetrics and Gynecology of the State University of Milan, Italy.
  
  
  METHODS
  Thirteen patients with deep endometriosis and ureteral involvement. Mean age of patients was 36.8 years (range, 31-48 years).
  
  
  METHODS
  Ureteroneocystostomy with a psoas hitch. Indications for performing psoas hitch ureteroneocystostomy were severe hydronephrosis, radiologic evidence of ureteral stricture measuring >4 cm, and the impossibility of performing ureterolysis.
  
  
  METHODS
  Impact on urodynamic parameters of bladder psoas hitch ureteroneocystostomy.
  
  
  RESULTS
  All patients showed normal bladder capacity 3 months after surgery. Two patients presented with stress incontinence immediately after surgery, which almost completely subsided at 3 months' follow-up. In 4 patients the bladder was also involved; in these cases a bladder resection was performed, followed by ureteral reimplantation. Follow-up was at 6 months from surgery and then every 6 months thereafter, in which patients underwent urogynecologic examination, completed a questionnaire on urinary symptoms, and underwent renal ultrasound evaluation with no evidence of recurrence of obstructive uropathy.
  
  
  CONCLUSIONS
  On the basis of the results of the present study, bladder psoas hitch along with ureteral resection and ureteroneocystostomy for infiltrating endometriosis do not seem to have a negative impact on urodynamic parameters.
