Urologists are experiencing difficulties managing ureteral strictures (US). Several treatment options have been used to treat US. Here, we present two patients with US. The first case is a 49-year-old woman with a history of squamous cell carcinoma of the cervix, status postlaparoscopy-assisted vaginal hysterectomy and radical parametrectomy, and bilateral pelvic lymph node dissection with recurrence. She regularly underwent double-J catheterization for bilateral US. The second case is a 66-year-old woman with a history of serious papillary adenocarcinoma of the endometrium, poststaging laparotomy with extrafascial hysterectomy + bilateral salpingo-oophorectomy + bilateral pelvic, common iliac, and para-aortic lymph node dissection + omentectomy. She regularly underwent double-J catheterization because of bilateral US. Allium stents have been used to treat US. Hydronephrosis improved in both patients. Renal function improved in one patient. A new self-expanding, large-caliber ureteral stent is another treatment option for patients requiring internal ureteral drainage.

Intrauterine devices (IUDs) are one of the most popular reversible contraception methods. However, if an event related to them is unanticipated, or if they are not located when missing, it can be dangerous. We present a case of chronic lower abdomen pain and recurrent urinary tract infection ongoing for 1.5 years. Despite the patient undergoing laparoscopic uterine myomectomy, her symptoms had not improved. The patient visited a genitourinary clinic for lower urinary tract symptoms and accepted cystoscopy and electrohydraulic lithotomy. Incidentally, a part of an IUD was found in the calculus. This case highlights the need for careful diagnosis and for locating missing IUDs to avoid serious complications.

Background: Wilms' tumor (nephroblastoma) is the most common solid primary renal malignancy in children but extremely rare in adult population. We report the clinical presentation and therapeutic results of our adult Wilms' tumor patients and review the previous literatures about diagnosis and treatments. Methods: A retrospective review was carried out to investigate the patients with adult Wilms' tumor at the Tri-Service General Hospital during a 35-year period (1980–2014). Seven patients ≥16 years old (one female and six males; median age at the time of diagnosis of 24 years; range: 21–48 years) were staged according to the National Wilms' Tumor Study staging system as follows: three patients had Stage II disease, two patients had Stage III disease, and two patients had Stage IV disease. All statistical values were represented as mean ± standard deviation. All tests were two-sided, with P < 0.05 considered statistically significant. All statistical analyses were carried out using SPSS software (IBM, Armonk, NY, USA). Results: The most common clinical presentation is flank pain (57%) followed by palpable mass (43%). Only one patient presented with gross hematuria. Four patients underwent renal arteriography, which all disclosed irregular, tortuous vessel pattern with faint tumor stain. All patients underwent radical nephrectomy (one – hand-assisted laparoscopic nephrectomy and six – open transperitoneal nephrectomy). Two patients developed lung metastases after radical surgery. Six patients received multimodal therapy, including surgery, chemotherapy, and radiation therapy. The mean disease-free survival is 81 months. The 3- and 5-year survival rates are 83% and 71% separately. Conclusions: Selective renal arteriography could provide a valuable diagnostic hint in adult Wilms' tumor. Using multimodality therapy, improved prognosis could be achieved.

Perirenal hematoma after extracorporeal shock wave lithotripsy (ESWL) is an unusual but underdiagnosed complication. Most hematomas are asymptomatic, but severe complications are possible, which may require intervention such as a blood transfusion. We present the case of a 41-year-old Asian man suffering from a symptomatic huge perirenal/subcapsular hematoma with scrotal hematoma after ESWL; we reviewed the literature and examined the possible risk factors and treatments. This case was a very rare presentation of hematoma extension into the scrotum region from an ipsilateral perirenal hemorrhage caused by shock wave lithotripsy treatment.

We aimed to explore the associations between different lipid profiles and semen quality in a large-scale general male population. Sperm concentration, total sperm motility, progressive motility, and normal sperm morphology of total 7601 participants were recorded. The association of these semen parameters with the triglyceride, total cholesterol, high-density lipoprotein, low-density lipoprotein, and very low-density lipoprotein of serum lipid profiles was analyzed. Sperm concentration was statistically positively correlated with triglyceride and very low-density lipoprotein (adjusted P = 0.001 and P = 0.005, respectively). Total sperm motility and progressive motility were statistically increased with increasing low-density lipoprotein and cholesterol levels (both adjusted P = 0.008 and P < 0.001, respectively). The similar J-shaped associations (high-low-low-high) were noted between individual lipid profile and normal sperm morphology, especially low-density lipoprotein and cholesterol with statistical significance (adjusted P = 0.017 and P = 0.021, respectively). The prevalence of abnormal total sperm motility and progressive motility was decreased in participants with high levels of cholesterol (P = 0.008 and P = 0.019, respectively), and the reverse J-shaped associations (low-high-high-low) were noted between high-density lipoprotein, triglyceride, very low-density lipoprotein, and the prevalence of abnormal normal sperm morphology (P = 0.010, P = 0.037, and P = 0.025, respectively). A high cholesterol level was associated with better sperm motility. Similar J-shaped associations were noted between all lipid profiles and normal sperm morphology; meanwhile, the reverse J-shaped trends were identified between them and abnormal normal sperm morphology prevalence.

Background: This study investigated the correlation between epicardial adipose tissue (EAT), a measure of central obesity, and sexual function in males with vasculogenic erectile dysfunction (ED). Materials and Methods: The study was a cross-sectional study of selected males with ED aged

Intravesical Bacillus Calmette–Guerin (BCG) is usually a well-tolerated treatment for urethelial carcinoma of the bladder. A 60-year-old male endured multiple erythematous white-scaled maculopapules over his trunk, back, and four extremities after 2 months of the 6-weekly intravesical instillation of BCG. Skin biopsy revealed parakeratotic hyperkeratosis, intracorneal neutrophilic Munro's abscess, and acanthosis. Guttate psoriasis was diagnosed, and he was treated successfully with topical steroid and narrow band UV-B phototherapy. We present the first Asian case of guttate psoriasis associated with intravesical BCG immunotherapy and review the literatures.
