[Transurethral endoureteropyelotomy].
Transurethral endoureteropyelotomy (TE) finds application in the treatment of the upper urinary tract (UUT). The method implies transurethral dissection of the stricture with "cold" knife, endoscopic scissors, hook-like electrode or laser applicator under roentgenoendoscopic control with subsequent intubation of the stricture by internal stent for 4-6 weeks. Since 1992 TE has been performed in 31 patients (19 males, 12 females) aged from 13 to 70 years for pelviureteral and ureteral strictures (19 and 12 cases, respectively). The length of the narrowing varied from 0.4 to 2.7 cm, 7 patients had congenital and 24 acquired UUT strictures. 26 patients were followed up for 6-48 months. Good therapeutic results (absence of the symptoms and pyeloectasis, improvement of renal function) were observed in 22 (85%) patients. Serious postoperative complications were represented by a trauma of the "crossing" arteries in the pelviureteral zone. To avoid it, a precise preoperative diagnosis of the vascular bed is required.
