Cases of self-inserted foreign bodies in the male urethra and urinary bladder are unusual. In most cases, the type of foreign body can be identified by taking a history or from radiological findings; sometimes, however, it is difficult to identify the foreign body because of decreased mental capacity of the patient or unknown radiological characteristics of the foreign body. We experienced a chronic alcoholic patient with septicemia and penile necrosis in whom a fragment of mirror glass had passed through the urethra into the bladder. The glass, 2 cm in length and 0.7 cm in diameter, was detected by cystoscopy and was removed by using a resectosope. We report a case of urosepsis due to a glass particle that had passed into the bladder after being self-inserted into the urethra. We present the evaluation, imaging, and management of the condition and the unique complications subsequent to the self-insertion of an intraurethral foreign body. Our case was unique in that this is the first reported case of urosepsis induced by an intraurethral foreign body that resulted in a retroperitoneal abscess and penile glans necrosis. CASE REPORTA 57-year-old male visited the emergency room because of worsening fever, right flank pain, and gross hematuria lasting 3 days. A review of his medical history determined that he underwent an operation 7 years previously because of an abdominal stab wound. He was a chronic alcoholic and was mentally challenged. Before visiting our hospital, he had been admitted to another hospital for complaints of voiding difficulty and abdominal discomfort; he was exam-

PurposeA morphologic contour method for assessing an exophytic renal mass as benign versus malignant on the basis of the shape of the interface with the renal parenchyma was recently developed. We investigated the usefulness of this morphologic contour method for predicting angiomyolipoma (AML) in patients who underwent partial nephrectomy for small renal masses (SRMs).Materials and MethodsFrom January 2004 to March 2013, among 197 patients who underwent partial nephrectomy for suspicious renal cell carcinoma (RCC), the medical records of 153 patients with tumors (AML or RCC) ≤3 cm in diameter were retrospectively reviewed. Patient characteristics including age, gender, type of surgery, size and location of tumor, pathologic results, and specific findings of the imaging study ("ice-cream cone" shape) were compared between the AML and RCC groups.ResultsAML was diagnosed in 18 patients and RCC was diagnosed in 135 patients. Gender (p=0.001), tumor size (p=0.032), and presence of the ice-cream cone shape (p=0.001) showed statistically significant differences between the AML group and the RCC group. In the multivariate logistic regression analysis, female gender (odds ratio [OR], 5.20; 95% confidence interval [CI], 1.45 to 18.57; p=0.011), tumor size (OR, 0.34; 95% CI, 0.12 to 0.92; p=0.034), and presence of the ice-cream cone shape (OR, 18.12; 95% CI, 4.97 to 66.06; p=0.001) were predictors of AML.ConclusionsThis study confirmed a high incidence of AML in females. Also, the ice-cream cone shape and small tumor size were significant predictors of AML in SRMs. These finding could be beneficial for counseling patients with SRMs.

PurposeWe investigated whether the Valsalva leak point pressure (VLPP) is valuable for predicting postoperative outcome measurement after transobturator suburethral tape (TVT-O) implantation for treating stress urinary incontinence (SUI) in women.Materials and MethodsA total of 204 female patients who underwent TVT-O placement for treatment of SUI from March 2008 to February 2012 were enrolled in this retrospective study. All patients completed the incontinence quality of Life questionnaire (I-QoL), a self-reported quality of life measure specific to urinary incontinence, and the cure rate of incontinence was measured before and 6 months after surgery. Cure was defined as no leakage of urine postoperatively both subjectively and objectively. We compared pre- and postoperative I-QoL scores according to preoperative VLPP and Stamey grade.ResultsThe numbers of patients with Stamey grades I, II, and III were 99 (48.5%), 84 (41.2%), and 21 (10.3%), respectively. A total of 30 (14.7%), 87 (42.6%), and 87 patients (42.6%) showed VLPP≤60, 6090 cm H2O, respectively. Preoperative VLPP was not significantly different according to preoperative I-QoL or change in I-QoL after surgery. However, I-QoL after surgery improved in patients with a high preoperative Stamey grade (p=0.001).ConclusionsVLPP was not a factor related to surgical outcome from the midurethral sling procedure. Stamey grade rather than VLPP was important for predicting subjective quality of life and improved incontinence-related quality of life after surgery.

A histological inflammatory finding at the initial prostate biopsy was negatively associated with prostate cancer detection in repeat biopsy. This result could be useful to determine the need for repeat prostate biopsy in patients with persistently elevated prostate-specific antigen.

PurposeWe investigated the efficacy of ketoconazole and estramustine before chemotherapy for treating patients with progressive castration-resistant prostate cancer (CRPC) after anti-androgen withdrawal syndrome.Materials and MethodsEighty-four patients who were diagnosed with CRPC and were treated between 2005 and 2009 were included. Thirty-nine patients were treated with 600 mg of ketoconazole and 10 mg of prednisolone per day (group I), and 45 patients were treated with 560 mg of estramustine per day (group II). The prostate-specific antigen (PSA) response, progression-free survival, and side effects were compared.ResultsThe median age of the patients, PSA level, and follow-up period were 72 years, 48.5 ng/ml, and 4 months (range, 1 to 29 months), respectively. The overall PSA response rate was 35.7%, and the PSA response rates were 33.3% for group I and 37.8% for group II (p=0.672). The median progression-free survival times were 8 months (95% confidence interval [CI] 5.9-10.1) overall, 5 months (95% CI 1.6-8.3) in group I, and 8 months (95% CI 5.9-10.0) in group II (p=0.282). The most common complications in groups I and II were nausea and vomiting (51.3%) and anemia (77.8%), respectively. Nausea and vomiting and hepatotoxicity were observed more often in group I, and gynecomastia, neutropenia, and anemia were observed more often in group II. The toxicities of each adverse effect were ≤grade 2.ConclusionsWith a resultant PSA decline and mild adverse effects, both ketoconazole and estramustine are worth consideration as treatment options for progressive CRPC patients after primary hormonal therapy.
