ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the benefit of placement of dual double-J stents following high-pressure balloon angioplasty for treatment of ureter-ileum anastomosis stricture after total bladder resection.</p><p><b>METHODS</b>Seventeen patients (11 males and 6 females, mean age 56.65±6.28 years, 23 sides) undergoing total bladder resection were included in this study. Unilateral and bilateral ureteral stricture occurred postoperatively in 11 and 6 patients, respectively; 13 patients had ureter-ileum bladder anastomosis stricture after ileal bladder substitution, and 4 patients had ureter-ileum stricture after orthotopic construction of ileal neobladder. The control group consisted of 21 patients undergoing open surgery.</p><p><b>RESULTS</b>In the double-J stenting group, the effective rate was 82.6% (19/23), similar to that of 85.7% (18/21) in the control group (P>0.05). Compared with the control group, the stenting group showed a significantly reduced mean time of operation (87.42±10.35 min vs 34.12±7.52 min, P<0.05), intraoperative blood loss (203.16±32.67 ml vs 21.54±6.15 ml, P<0.05), and mean postoperative hospital stay (10.12±1.19 vs 3.24±0.35 days, P<0.05).</p><p><b>CONCLUSION</b>As a safe and minimally invasive approach to the management of ureter-ileum bladder anastomosis stricture, placement of dual double-J stents following high-pressure balloon angioplasty produces a effect comparable with that of open surgery.</p>
