[Technical solution for single kidney patients with multiple ureteral neoplasms].
When ureteral length is extensively compromised, preservation of the kidney without recurring to external urinary diversion may be attempted by various techniques. The choice depends on the extension and localization of the defect. We report a technique solution performed in a patient with multiple ureteral tumors and solitary kidney. A 70-years old underwent TURB for superficial bladder cancer and right nephroureterectomy for upper urinary tract tumor. He was admitted for hematuria and renal failure which need a percutaneous nephrostomy. Urography and pielo-RMN showed multiple and irregular defects of proximal left ureter. We performed a left ureterectomy with ureteral substitution by tailored and retroperitonealized ileal segment with simultaneous ileal bladder augmentation. The six months follow-up including serum creatinine, sonography, urodynamic evaluation, urinary cytology, excretory urogram and pielo-RMN shows good results. Ureteral replacement with ileum is indicated only for extensive ureteral diseases in which ureteroneocystostomy or vesical Psoas hitch and/or Boari bladder flap are not feasible. With particular attention to surgical aspects as tailoring ileum (to improve propulsion of urinary bolus, limit the absorbing surface area and decrease mucus formation) and the use of an ileal segment longer than 15 cm (to prevent reflux) and with an accurate patient selection, we think that this procedure can assure satisfactory results also in difficult cases.
