RESUMEN
Objective To explore the related risk factors of renal function after partial nephrectomy,and provide the reference for clin-ic. Methods The data of 31 patients with small renal cancer in our hospital from January 2010 to June 2014 were analyzed. Before and after the treatment,the relationship of renal glomerular filtration rate ( GFR) with the change and clinical pathological factors were analyzed,the single factor analysis used t test,multiple factors analysis adopted multi-factor unconditioned logistic regression analysis. Results Single fac-tor analysis results showed that renal function after partial nephrectomy was closely related to the age,diabetes mellitus,blocking time,the size of the tumor,renal volume reduction ratio,the difference was statistically significant (P<0. 05). Many factors of logistic regression showed that it was closely related to the age,blocking time,renal volume reduction ratio(P<0. 05). Conclusion The age,blocking time,renal vol-ume reduction ratio are risk factors for renal function after partial nephrectomy.
RESUMEN
Objective To evaluate the clinical methods and results of endoscopic-assisted catheterization in the treatment of bulbous urethral injury . Methods The clinical data of 19 cases of bulbous urethral injury from July 2004 to September 2012 managed by ureteroscopic catheterization were retrospectively analyzed . Results The procedures were successfully completed in all the 19 cases.Foley catheters were removed in 4-8 weeks after the surgery and all cases had unobstructed ureter after the removal of the catheter.Urethral dilatation was done regularly for 4 times and all the cases were followed up for 6-12 months afterwards.The follow-up showed urinary flow rate was more than 15 ml/s, and no urethral stricture , urinary incontinence or other complications occurred.Erection of penis was not obviously affected compared with preoperative condition . Conclusion Endoscopic-assisted catheterization is effective in the treatment of bulbous urethral injury .
