Inverted papilloma of the urinary tract is a rare benign lesion. We report, to our knowledge, the first case of inverted papilloma of the prostatic urethra arising in a juvenile. Our patient was referred for evaluation of painless, gross hematuria and voiding difficulty. Transrectal sonography demonstrated a 1.4 cm papillary lesion on the medial aspect of the prostatic urethra. Cystoscopy showed a solitary, papillary tumor on the prostatic urethra. Transurethral resection was performed and histological examination showed an inverted papilloma.

PURPOSE: The purpose of this study is to evaluate the preoperative factors that influenced postoperative sperm concentration after vasovasostomy. MATERIALS AND METHODS: We retrospectively reviewed 97 consecutive single-layer vasovasostomy procedures performed by a single surgeon between March 2003 and September 2010. The patients were stratified into three groups based on sperm concentration at 1 month follow-up: group I-azoospermia, group II-oligospermia, and group III-normal. We evaluated the preoperative factors that may have influenced sperm concentration at postoperative 1 month. Patients with serial semen analysis were divided into four groups according to the change in postoperative sperm concentration at the 6-month visit: group II-N-from oligospermia to normal, group II-O-from oligospermia to oligospermia, group III-O-from normal to oligospermia, group III-N-from normal to normal. We compared the pregnancy rate among the four groups. RESULTS: The mean obstructive interval was 9.69 years in group I, 6.02 years in group II, and 7.82 years in group III. There were significant differences found among the groups (p=0.035). There was significantly different change in sperm concentration, sperm motility, and sperm morphology between each of the groups. A total of 32 patients underwent serial semen analyses at 1 month, 3 months, and 6 months after vasovasostomy. There was no significant difference in patient age, obstructive interval, or follicle-stimulating hormone among the groups. The natural pregnancy rate in group II-O was lower than that in group II-N, and in group III-O was lower than that in group III-N. However, there was no significant difference among each of the groups. CONCLUSIONS: The sperm concentration after vasovasostomy was significantly related to the obstructive interval between vasectomy and reversal.

PURPOSE: The purpose of this study was to evaluate the annual changes in prostate variables and style of surgical treatment of patients with benign prostatic hyperplasia (BPH) over the past 12 years. MATERIALS AND METHODS: The subjects were 918 patients (January 1999-November 2010) who were treated by either open prostatectomy or transurethral resection of prostate (TURP). Every year, the performance ratio between open prostatectomy and TURP was evaluated. Before surgery, total and transitional zone volumes of the prostate were measured by transrectal ultrasonography (TRUS). After surgery, resection weight and residual volume of the prostate were measured by TRUS. RESULTS: From 2001 through 2010, the performance ratio of TURP increased greatly from 89% to 97%. During 1999 to 2010, the total volume of the prostate increased from 40.0 cc to 55.0 cc in the TURP group and from 74.1 cc to 116.7 cc in the open prostatectomy group. During 1999 to 2010, the mean resection volume of the TURP group increased from 2.3 cc to 20.1 cc. Also, the mean resection volume of the open prostatectomy group increased from 59.3 cc to 114.3 cc. During 1999 to 2003, the resection time of the TURP group decreased from 72.9 minutes to 43.2 minutes. CONCLUSIONS: During 1999 through 2010, the performance ratio between open prostatectomy vs TURP was high for TURP. The total volume and resection volume of the prostate increased annually, and the resection time decreased annually.

Lower urinary tract symptoms (LUTS) are a cluster of voiding symptoms, such as weak stream, hesitancy, intermittency, urinary frequency, urgency, and nocturia. LUTS are frequent in elderly men and it considered the ultimate clinical symptoms of benign prostatic hyperplasia. With aging, male hypogonadism is increased which is defined as decreased ability of the testes to produce sperm and sex steroids because of a pituitary/hypothalamic, or testicular deficiency. In academic andrology associations, the term “male hypogonadism” is commonly used to categorize testosterone deficiency. Testosterone deficiency syndrome (TDS) is defined as a decrease in serum testosterone accompanied by symptoms such as libido decrease, depressive disorder, erectile dysfunction, and fatigue. Although the mechanism about testosterone-replacement therapy (TRT) effects on men with hypogonadism is not yet identified, TRT has been shown to effectively relieve the symptoms of TDS as well as LUTS by several studies. Although the present review demonstrates the effectiveness and safety of TRT in men with TDS by prior studies, future large scale of clinical trials should be conducted to present more high-quality evidence to clinicians and patients.

Germ cell tumors (GCTs) of the testis are rare, but are the most common cancer in young men. GCTs may consist of one predominant histologic pattern or may represent a mixture of multiple histologic types. For treatment purposes, two broad categories are recognized: 1) pure seminoma and 2) others, which together are termed nonseminomatous GCTs (NSGCTs). In general, seminoma tends to be less aggressive, to be diagnosed at an earlier stage, and to spread predictably along lymphatic channels to the retroperitoneum before spreading hematogenously to the lung or other organs. Compared with NSGCTs, seminoma is exquisitely sensitive to radiation therapy and platinum-based chemotherapy. NSGCTs are usually mixed tumors and teratoma often exists at the sites of metastasis with other GCT elements; cure often requires chemotherapy to kill the chemosensitive-components and surgery to remove the teratomatous components. The main factors contributing to excellent cure rates of GCTs are careful staging at diagnosis; adequate early treatment using chemotherapeutic combinations, with or without radiotherapy and surgery; and very strict follow-up and salvage therapy. We review several clinical studies and summarize the current trends in the management of GCTs.
