ABSTRACT
<p><b>OBJECTIVE</b>To analyse different factors related to the occurrence of bladder neck contracture (BNC) and to find possible ways of reducing this complication.</p><p><b>METHODS</b>All putative factors and the numbers of BNC cases were studied with statistical analyses in 1,017 cases that had undergone transurethral resection of the prostate (TURP).</p><p><b>RESULTS</b>The morbidity of BNC after TURP was significantly higher than that of open operations. Small size of the prostate, longer time of operation, higher power in resection and prostatitis were factors of BNC.</p><p><b>CONCLUSION</b>Properties of the prostate and electrical current injuries of resection are the primary factors of BNC. The selection of patients and techniques of TURP are most important in decreasing the morbidity of BNC.</p>

Objective: To establish a rabbit unstable bladder and Partial Bladder Outlet Obstruction (BOO) model, and to study on urodynamic changes. Methods: 30 male New Zealand rabbits were divided into control group and operative group. After 8 weeks, urodynamic changes were determined after they were anaesthetized by ketamine and droperidol. Results: Prominent changes of Main urodynamic parameters were found between the operative group and control group. The incidence rate of unstable bladder was 60%. Conclusion: The method of establishing rabbit model of Partial BOO is successful. It provides a platform for the study on the changes of pathology and pathophysiology of human chronic partial BOO and treatment of this kind of diseases.
