Congenital diverticulum is a very rare disease of the urethra in which there is a sacculus enlargement on its ventral surface. We present a Case of a 2-year-old boy with symptoms of urinary hesitancy and swelling in the penoscrotal angle that appears during micturition. The diagnosis of urethral diverticulum is confirmed by retrograde urethrography and voiding cystogram. An open operation was performed - diverticulectomy and primary repair of the urethra.

Hydatid disease is a condition affecting mainly the liver or, to a lesser extent, the lungs. We present an uncommon case of a primary renal echinococcosis in a young man complaining of intermittent hematuria, dull flank pain, and palpable mass in the left lumbar and lateral abdominal area which increases its size over time. After initial self-treatment with painkillers and antibiotics, the patient was referred to a urological clinic, where the physical examination revealed a large tumour mass in the left kidney. Ultrasound showed a large multilocular renal cyst, with a CT highly suspicious for renal echinococcosis (15×12.8×24.2 cm). Serological tests confirmed presence of IgG against Echinococcus. The patient was operated using the lumbar approach and nephrectomy was performed. The man recovered completely after surgery without the need for further treatment.

Introduction: Pediatric urolithiasis is a very specific and challenging problem in the field of modern urology. Currently, there are three major methods for kidney stone removal: the extracorporeal shock wave lithotripsy (ESWL), the retrograde intrarenal surgery (RIRS), and the percutaneous nephrolithotomy (PCNL), the latter one proving to be an efficient and safe monotherapy of stones even with larger burden. Different sizes of nephroscopes are used (standard, mini, micro), where smaller size is logically correlated with safer profile, especially in pediatric population.Aim: To analyze the initial experience in using PCNL in children for the treatment of kidney concrements – rates of successful stone removal and registered complications.Materials and methods: Twenty-six PCNL procedures of 25 children were performed – both standard and mini. The age ofpatients, size of the stones, operating time, changes in hemoglobin levels, duration of hospital stay, and the postoperative complications were recorded, analyzed and compared to data reported in current relevant literature.Results: The mean age of patients was 9±5.2 years (15 boys and 10 girls). The average size of concrements subjected to nephrolitholapaxia was 16±0.7 mm, most of the cases being single stones. The average operative time was 150±33.4 min, and the average hospital stay was 4.1±1.5 days. The percentage of stone free children postoperatively was 94%. Complications included blood loss requiring transfusion in 1 patient (4%), postoperative urinary tract infection and fever (2 patients), and self-limiting hematuria in 16%.Conclusions: PCNL is an effective and safe alternative in the management of nephrolithiasis in children. It is a method of choice for the treatment of concretions not suitable to treat with extracorporeal lithotripsy and after a qualitative selection of patients.

COVID-19 disease causes acute respiratory infection – pneumonia. It is associated with an increased risk of complications such as hypercoagulopathy, which leads to thromboses. We present a case of a young man presenting with typical SARS-CoV-2 symptoms (fever, cough, fatigue, and dyspnea), who experienced ischemic priapism, most probably due to thrombosis of penile vessels caused by the novel coronavirus infection. After prompt treatment of the priapism with punctures and irrigation, lasting penile detumescence was achieved. However, despite younger age, lack of serious comorbidities and administration of anticoagulants, priapism was followed by a fatal pulmonary embolism some days later.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare congenital disorder affecting female reproductive system (agenesis of uterus and upper part of vagina) alone (type 1), or associated with abnormalities of other organs and systems (type 2). We report a case of a 21-year-old woman diagnosed with MRKH due to primary amenorrhea during puberty and operated for formation of neovagina. She was admitted to the Department of Urology with abdominal pain and oligoanuria, where the physical examination and imaging studies revealed a malformation of the upper urinary tract: a solitary dystopia of kidney in the pelvis with stenosis of ureteropelvic junction and hydronephrosis. After initial desobstruction with a DJ stent, a pyeloplasty was performed. Females with primary amenorrhea are often delayed with the diagnosis of potential MRKH syndrome, and those diagnosed with the syndrome should undergo detailed examination to exclude concomitant urinary abnormalities.
