PURPOSE: We prospectively evaluated the surgical outcomes of single scrotal incision orchiopexy in children with a palpable undescended testis compared with the traditional two incision orchiopexy. MATERIALS AND METHODS: A total of 398 orchiopexies (292 children) were included and randomly assigned to the single scrotal incision orchiopexy group (Group I, 147 children, 201 testes) or the traditional inguinal incision orchiopexy group (Group II, 145 children, 197 testes). The final number of patients enrolled (excluding those lost to follow-up) was 107 children (146 testes) in group I and 105 children (141 testes) in group II. Success was defined as no complications, postoperative intrascrotal location of the testis, and no conversion to the traditional inguinal approach. Surgical outcomes and complications were compared between the two groups. Testicular location, complications, and subjective satisfaction rate were assessed at the follow-up evaluation at least 12 months postoperatively. RESULTS: The overall success rate in group I was 92.5% in 135 of 146 testes; the remaining 9 testes required conversion to traditional two incision orchiopexy. In group II, orchiopexy was successful in 136 of 141 testes (96.5%). The operation time and hospital stay were significantly shorter in group I (40.5+/-25.9 minutes, 2.1+/-0.8 days) than in group II (62.3+/-35.6 minutes, 2.5+/-0.7 days), respectively (p<0.001, p=0.03). Postoperative complications were found in two cases (hematoma, wound dehiscence) in group I and in one case (wound dehiscence) in group II; all cases with complications recovered with conservative care. The subjective rate of satisfaction with the cosmetic result was 96.6% in group I and 96.5% in group II (p=0.97). CONCLUSIONS: We conclude that single scrotal incision orchiopexy is a simple technique that is associated with a shorter operation time and hospital stay than the traditional method and that is more feasible cosmetically.

PURPOSE: We 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 METHODS: Eighty-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. RESULTS: The 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 < or =grade 2. CONCLUSIONS: With 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.

PURPOSE: The objective of this study was to investigate the diagnostic accuracy of multi-detector computerized tomography urography (MDCTU) for the detection of bladder tumors. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 143 patients who were scanned by use of 64-channel MDCTU and who underwent cystoscopy due to painless hematuria or a clinical suspicion of bladder tumor. We examined the accuracy of MDCTU for the detection of bladder tumors by comparing the results obtained by MDCTU with those obtained by cystoscopy. The associations between tumor characteristics, frequency of transurethral resection (TUR), and bladder volume and detectability of bladder tumors on MDCTU were also analyzed. RESULTS: Of 143 patients, 50 patients had a history of urothelial carcinomas. In these patients, the sensitivity and specificity of MDCTU were 60.0% and 80.0%, respectively. In 93 patients without previous urothelial carcinomas, the sensitivity and specificity of MDCTU were 86.7% and 96.8%, respectively. Falsely diagnosed cases had a smaller distended bladder volume (p=0.014) and a smaller tumor size (p=0.022) than did true diagnosed cases. The false-negative rate increased when the bladder tumor was located at the bladder neck. In the univariate analysis, the tumor location, size, frequency of TUR, bladder volume, and initial hematuria were associated with detectability by MDCTU (p<0.05). CONCLUSIONS: To improve the accuracy of MDCTU for diagnosing bladder tumors, bladder filling is recommended. Thus, cystoscopy should be considered as a standard diagnostic tool for bladder tumors even in patients with normal MDCTU results, especially in the evaluation of recurrent, bladder neck-located, small, or sessile bladder tumors.

PURPOSE: The aims of this study were to investigate the clinical significance of transrectal ultrasonography (TRUS) and the efficacy of dutasteride (5alpha-reductase inhibitor) in patients with hemospermia. MATERIALS AND METHODS: From January 2005 to December 2008, 60 patients with hemospermia were enrolled in the study. All patients underwent a digital rectal examination and TRUS; serum prostate specific antigen was also measured. The management of hemospermia was one of the following: watchful waiting, dutasteride treatment, or antibiotics with dutasteride. RESULTS: Thirty-four patients (56.7%) had positive findings on TRUS. There were 16 cases (26.7%) of prostate calcification, 13 cases (21.7%) of ejaculatory duct cyst, 3 cases (5%) of ejaculatory duct calcification, a case of seminal vesicle inflammation, and a case of ejaculatory duct dilation. Dutasteride treatment resulted in improvement of symptoms in 87.9% (29/33) of the cases, whereas treatment with antibiotics or antibiotics with dutasteride resulted in a 100% (6/6) success rate. However, among 14 watchful waiting patients, only 3 patients (21.4%) showed an improvement of symptoms. CONCLUSIONS: This study showed that TRUS is an easy and effective method for the assessment of hemospermia, and also revealed that dutasteride could be a useful agent in the treatment of hemospermia.

PURPOSE: We evaluated men with documented chronic prostatitis and elevated serum prostate-specific antigen (PSA) to determine whether treatment with antibiotics and anti-inflammatory drugs can lower serum PSA and the cancer detection rate in patients with post-treatment PSA <4 ng/ml. MATERIALS AND METHODS: Eighty-six men who presented with serum PSA greater than 4 ng/ml and who were subsequently diagnosed with chronic prostatitis with greater than 10 white blood cells per high power field in expressed prostatic excretions were included in this prospective study. Patients meeting these criteria underwent treatment with a 4-week course of antibiotics and nonsteroidal anti-inflammatory agents. Follow-up PSA and transrectal ultrasonography-guided prostate biopsy were performed within 2 months of treatment for all patients. RESULTS: Mean patient age was 56.2 years (range, 37-72 years). Mean PSA (ng/ml) decreased by 33.8%, from 8.12 (range, 4.02-24.8) to 5.37 (range, 1.35-12.94), after treatment (p=0.001). Pathological studies revealed prostate cancer in 18 cases (20.9%), chronic inflammation in 64 (74.4%), and benign prostatic hypertrophy in 4 (4.7%). The prostate cancer detection rate according to the follow-up PSA level, below 2.5, from 2.5 to 4.0, and above 4.0, was 13.3% (2/15), 13.6% (3/22), and 26.5% (13/49), respectively. CONCLUSIONS: When chronic prostatitis with elevated PSA is identified, antibiotic and anti-inflammatory treatment can lower these PSA levels. However, the possibility of prostate cancer remains in patients whose PSA level decreases to less than 4 ng/ml, even in those with a PSA level less than 2.5 ng/ml.

PURPOSE: To investigate patients who had transrectal ultrasonography (TRUS)-guided prostate biopsy to define the role of the serum testosterone level in predicting prostate cancer risk and its association with a high Gleason score. MATERIALS AND METHODS: A total of 568 patients who underwent prostate biopsy were entered in this study. We divided the patients into two groups according to serum testosterone level (median level, 3.85 ng/ml): the high-testosterone group (n=285) and the low-testosterone group (n=283). Multivariate regression analysis was used to define the effect of age, prostate volume, serum prostate-specific antigen (PSA) level and PSA density, and serum testosterone level on the risk of prostate cancer and a high Gleason score. RESULTS: Baseline characteristics did not differ significantly between the two groups. Compared with the high-testosterone group, the low-testosterone group had a significantly higher prostate cancer incidence (38.9% vs. 29.5%, p=0.018). Factors associated with an increased risk of prostate cancer were increased age (odds ratio [OR]=1.08, 95% confidence interval [CI]=1.25-3.16, p=0.001), a high serum PSA level (OR=3.35, 95% CI=2.63-4.25, p=0.001), a low prostate volume (OR=0.183, 95% CI=0.11-0.30, p=0.001), and a low serum testosterone level (OR=1.99, 95% CI=1.25-3.16, p=0.001). Among these, only the serum PSA level was a strong predictor of high-grade prostate cancer (Gleason score > or =7) (OR=2.19, 95% CI=1.57-2.95, p=0.001). CONCLUSIONS: Patients with lower levels of serum testosterone had a higher risk of prostate cancer than did patients with high serum testosterone. Even though a lower serum testosterone level was a predictor of prostate cancer risk, it was not associated with an increased risk of high-grade prostate cancer.

We report a case of a metachronous transitional cell carcinoma (TCC) of the penile urethra in an elderly male after nephroureterectomy. The patient had a history of right nephroureterectomy 18 months previously due to TCC of the upper urinary tract. A solitary urethral recurrence from a TCC of the upper urinary tract is rare. An anterior urethral recurrence of a TCC of the upper urinary tract has not been previously reported in the literature. The prognosis of a metachronous anterior urethral recurrence of an upper-tract TCC is poor.

PURPOSE: Androgen deprivation therapy (ADT) is associated with loss of bone mineral density (BMD). Preexisting bone losses in men with prostate cancer are of great concern because of accelerated bone loss during ADT. We sought to identify the risk factors associated with osteoporosis in Korean patients with prostate cancer who had not received ADT. MATERIALS AND METHODS: Patients who underwent biopsy of the prostate because of a high prostate-specific antigen (PSA) level or a palpable nodule in a digital rectal examination were included in this study. The patients (n=90) were divided into 2 major groups according to biopsy results: the prostate cancer group (group 1, n=41) and non-prostate cancer group (group 2, n=49). The age, body mass index (BMI), lifestyle, testosterone concentration, BMD, and disease variables in prostate cancer were obtained and analyzed prospectively. BMD of the lumbar spine and femoral neck was measured by dual-energy X-ray absorptiometry. RESULTS: In group 1, 41.4% had osteopenia (36.6%) or osteoporosis (4.8%); in group 2, 26.5% had osteopenia (22.4%) or osteoporosis (4.1%). The estimated mean T-score was significantly (p=0.037) lower in group 1 (-0.668+/-1.364) than in group 2 (-0.041+/-1.426). The significant factors correlated with BMD (T-score) in prostate cancer were age (p=0.012), serum testosterone level (p=0.019), and BMI (p=0.004). CONCLUSIONS: BMDs were lower in men with prostate cancer who had not received ADT than in the control group. Consideration should be given to counseling on risk factors and lifestyle issues in prostate cancer patients with old age, low serum testosterone, and slender stature before initiating ADT.

We report the case of a 58-year-old man with a multilocular prostatic cystadenoma in the retrovesical space that mimicked a pelvic cavity tumor. Multilocular prostatic cystadenoma is a rare form of benign prostatic hyperplasia that originates from the prostate with extensive spread into the pelvis. Histologically, the tumor consisted of glands and cysts lined by prostatic-type epithelium lying in a hypocellular fibrous stroma. For a cystic tumor adjacent to the urinary tract, ectopic prostatic cystadenoma is needed to be considered in the differential diagnosis of pelvic cavity tumors.

PURPOSE: The change of quality of life following a tension-free vaginal tape (TVT) and transobturator vaginal tape (TVT-O) procedure was investigated in patients with stress urinary incontinence. MATERIALS AND METHODS: We included 86 women with stress urinary incontinence who underwent the TVT or TVT-O procedure and followed up for at least 1 year. Preoperatively, the patients were evaluated with history taking, physical examination, urodynamics to determine abdominal leak point pressure (ALPP) and pre- and postoperative quality of life was evaluated by incontinence quality of life questionnaire (I-QoL). The success after operation was defined as the absence of any subjective complaint of leakage. RESULTS: The rate of cure of TVT and TVT-O procedure were 84%, 92% and the rate of improvement of them were 16%, 8%, respectively. Preoperative patient characteristics including uroflowmetric parameters and ALPP were comparable in the two groups. The I-QoL parameters one year after surgery were statistically significant increase in I-QoL scores in each groups. There were no serious or long-term complications related to both procedures. CONCLUSIONS: These data suggest that the TVT and TVT-O procedure are effective for treating female stress incontinence and also in the aspect of improving quality.
