Ureteroscopy-Assisted Laparoscopic Segmental Resection of Ureteral Stricture with a Modified Flank Position: Clinical Experience

To share the surgical technique that possesses the advantage of a perioperative ureteroscope without position change, which allows for a laparoscopic segmental resection of the ureteral stricture to be performed more precisely.Between 2006 January and 2015 December, 10 patients with a ureteral stricture received a laparoscopic segmental resection and ureteroureterostomy in our clinical institute. The etiology included stone, endometriosis, crossing vessel, and idiopathic benign ureteral polyp. With the advance of bilateral lower extremities extended and abducted, 1 assistant used a ureteroscope as a direct guide to the precise location of the stricture affected ureter. Thus, the surgeon was able to perform a more specific resection without an unnecessary excision, which may have compromised the blood supply or increased the tension at anastomosis.Five patients received the traditional transperitoneal laparoscopic approach, whereas the other 5 patients received a ureteroscopy-assisted laparoscopic segmental resection and ureteroureterostomy. The operating time appears to be no different between the two groups (124 minutes versus 142 minutes, P = .351), and, thus, no additional time is consumed for the ureteroscope procedure. After at least 1 year of follow-up, only 1 patient in the traditional laparoscopic group suffered from recurrence. One patient had a right ureteral stricture due to stone impaction, where with the advantage of a ureteroscope guide without change position, the operator was able to make a limited excision at the affected location. No complications related to the decubitus and bilateral leg in the extended position were noted.Ureteroscopy-assisted laparoscopic segmental resection of the ureter without a change in position is a feasible and safe procedure when dealing with a refractory ureter stricture. Although it is convenient, the surgeon should be aware of possible pressure sores at the dependent part.
