[Nephrureterectomy with endoscopic resection of the urinary bladder, ureteral ostium and terminal part in papillary tumors of the upper urinary tracts].

Short- and long-term results of endoscopically assisted nephrureterectomy were studied in 15 patients (7 males and 8 females aged 31-79 years) with papillary tumours of the upper urinary tracts (UUT). Of them, 11 patients have undergone transurethral endoresection of the urinary bladder, ostium and terminal part of the ipsilateral ureter followed by nephrureterectomy from the lumbotomic approach (technique 1) and 4 patients had nephrureterectomy followed by endoscopic intervention (technique 2). Results of standard open nephrureterectomy with resection of the bladder were analyzed retrospectively for 25 patients with papillary tumors of the UUT taken as control. It was found that transurethral endoscopic resection of the bladder, ostium and terminal part of the ipsilateral ureter in nephrureterectomy for papillary tumors of the UUT facilitates the performance, decreases duration and aggression of surgical intervention, diminishes number of complications, shortens hospital stay of the patients and their rehabilitation. Technique 1 is thought more ablastic and simple in performance.
