[A novel technique of ureterointestinal anastomosis for urinary diversion]

To introduce a novel technique of ureterointestinal anastomosis for urinary diversion and report the preliminary clinical data.

Between June 2007 and June 2011, a total of 50 patients underwent radical cystectomy and ileal neobladder for invasive bladder carcinoma or carcinoma in situ. A novel, separate and direct end-to-end technique for ureteral reimplantation to the entrance of a segment of ileum was applied. in all patients. Details are as follow. The entrance of afferent loop was divided equally in to two lumens. Then each ureter was directly, end-to-end anastomosed to the above lumens respectively after lengthwise incisions for 1.5 cm. The mean follow-up period was 22 months (range, 3 - 48 months).

Ureterointestinal anastomosis was performed successfully in 100 units. The operative durations were (18.4 ± 4.2) minutes. Ureteral stricture developed in 4 of 100 (4%) units and refluxing in 6 of 100 (6%) units. One patient with stricture was successful repaired by balloon dilation.

With low stricture and reflux rates, this novel procedure of ureterointestinal anastomosis is simple to handle and worthy of further promotion.
