Studer's bladder: functional results and morbidity in 33 patients

Objective : Several types of enterocystoplasty can be performed after cysto prostatectomy Sor cancer The objective of this study was to evaluate our 8- year experience with Studer's technique. Patients and Methods : The medical files of 33 patients were studied retros pectively The median age was 60 years. Bladder replacement was performed wh en frozen section histological examination of urethral biopsies was negativ e. The medina follow-up was 41 months. Continence was evaluated by means of a questionnaire. Patients not using any pads or only using pads as a preca ution were considered to be diurnally continent, and those using no more th an one pad per night were considered to be nocturnally continent. Results. Postoperative surgical morbidity consisted of two pel vic abscesse s, two cases of obstructive acute pyelonephritis, one occlusion, and three wound complications. Eight patients developed urethroneovesical stenosis an d seven ureters were reimplanted because of stenosis (two right ureters and five left ureters). Diurnal and nocturnal continence rates were 67% and 74% at 12 months. and 8 0% and 94% at 24 months, respectively: Seven patients developed acute pyelonephritis, renal function deteriorated in one patient (preoperatively renal failure) and one patient developed aci dosis. Conclusion : Studer's technique is a simple technique providing satisfactor y functional results while preserving the upper tract by means of a simple and original antireflux system (ileal ureter) with a median follow-up of 41 months, although it was associated with a considerable stenosis and pyelon ephritis rate.
