ABSTRACT

Objective:To explore the etiology of male urethral stricture,analyze the therapeutic strategies of urethral stricture,and summarize the complicated cases.Methods:The data of 183 patients with urethral stricture were retrospectively analyzed,including etiology,obstruction site,stricture length,therapeutic strategy,and related complications.Results:The mean age was 49.7 years,the average course was 64.7 months,and the constituent ratio of51 to 65 years old patients was 38.8% (71/183).The traumatic injury of patients accounted for 52.4% (96/183),in which the pelvic fracture accounted for 35.5% (65/183) and the straddle injury accounted for 16.9% (31/183).There were 54 cases of iatrogenic injury (29.5%).The posterior urethral stricture accounted for 45.9% (84/183),followed by the anterior urethral stricture (44.8%,82/183) and the stenosis (6.6%,12/183).A total of 99 patients (54.1%) received the end to end anastomosis,and 40 (21.9%) were treated with intracavitary surgery,such as endoscopic holmium laser,cold knife incision,endoscopic electroknife scar removal,balloon dilation,and urethral dilation.In the patients over 65-years old,the urethral stricture rate was 14.8% and the complication rate (70.4%) for transurethral resection of the prostate (TURP) was significantly higher than that of all samples (P< 0.01).Conclusion:Both the etiology of male urethral stricture and the treatment strategy have changed and the incidence of traumatic and iatrogenic urethral stricture has increased in recent 3 years.The main treatment of urethral stricture has been transformed from endoscopic surgery into urethroplasty.

ABSTRACT

Objective To investigate the diagnosis and treatment methods of traumatic renal infarction.Methods A retrospective analysis was performed on 6 cases of traumatic renal infarction treated between September 2008 and February 2013.There were 5 males and 1 female,at age of 5-65 years (average,36.2 years).Causes of injury included vehicle collisions in 4 cases and high falls in 2.Out of 6 cases,segmental renal infarction was identified in 2 and total infarction in 4.According to American Association for the surgery of trauma renal trauma grading system,2 cases were classified to grade Ⅳ and 4 to grade Ⅴ.Results Three cases were managed conservatively,which showed segmental infarction in 1 case and total infarction in 2.Three cases underwent surgical exploration,followed by partial nephrectomy in 1 case,left kidney removal plus partial pancreectomy in 1 and right kidney removal in 1.There were no major complications intraoperatively or postoperatively and no cases received blood transfusion.Period of follow-up was 3-34 months.In conservative management,there were no renal atrophies in segmental renal infarction cases and some degree of atrophies in total renal infarction cases,but none presented with arterial hypertension.Conclusions Enhanced CT is the preferred diagnostic tool for evaluation of traumatic renal infarction.Conservative therapy is the optimal option for most cases,but nephrectomy is reserved for cases of infection or renal hypertension.
