Purpose: The aim of this study was to determine the prevalence and disease-specific antimicrobial susceptibility of Escherichia coli in urinary tract infections (UTIs). Materials and Methods: A total of 862 patients older than 18 years of age, who were diagnosed with UTI between January 2013 and December 2015, were included. The results of urine culture, prevalence of extended-spectrum beta lactamase (ESBL)-producing E. coli, and antimicrobial susceptibility by disease were also examined. Results: A total of 862 uropathogens were isolated. Among then, E. coli accounted for 756 (87.7%) isolates. The susceptibility rates of E. coli to the following antimicrobial agents were as follows: ampicillin 29.4%, cefazolin 70.5%, ceftazidime 75.1%, cefotaxime 75.0%, cefepime 76.2%, cefoxitin 88.8%, amoxicillin-clavulanic acid 63.6%, trimethoprim-sulfamethoxazole 60.6%, gentamicin 71.4%, ciprofloxacin 73.0%, piperacillin/tazobactam 93.9%, amikacin 99.2%, imipenem 99.1%, and ertapenem 99.3%. The frequency of ESBL-producing E. coli strains was 24.6%. The antimicrobial susceptibility of UTI varied by each disease, but without statistical significance. Conclusions: It is necessary to regularly examine the disease-specific resistance rates to determine the appropriate empiric antibiotic treatment, and the national antibiotic usage policies must be reorganized according to the data obtained from these studies.

Epidermal cyst, a benign tumor, can occur after trauma and surgical interventions such as implanting epidermal keratinized squamous epithelial cells and sebaceous glands into the dermis and subcutaneous tissues. It can occur anywhere in the body. However, penile epidermal cysts are very rare. We present a case of a symptomatic penile mass of a 34-year-old male patient with a ruptured epidermal cyst.

Cystic enlargement of prostatic utricle, a vestigial remnant of mullerian duct, is a rare condition in males. The prostatic utricle distends with urine during voiding and then passively drains. Poor emptying leads to urine retention and stasis. Stone formation may result from obstruction. Patients present clinically with chronic urinary tract infection, hematuria, urethral discharge, epididymitis, and voiding dysfunction. We present a case of multiple stones in the enlarged prostatic utricle associated with hemospermia.
