Scrotal calcinosis is a rare benign pathology and its etiology is still discussed. The main complaint is mostly aesthetic. The treatment of extended forms is a one-staged excision. The aim of our study was to study clinical and anatomopathological aspects and report our surgical management of a case of diffuse scrotal calcinosis. We report a case of 24-year-old patient who consulted for painless scrotal nodules lasting for 2 years. Scrotal calcinosis diagnostic was based on clinical examination. The treatment was a one-staged scrotal excision taking all nodules and the plasty of the scrotum. The diagnosis was confirmed by a histopathological examination of surgical specimen.

Squamous cell carcinoma of the prostate is rare and represents 0.5% to 1% of prostatic carcinomas. Transformation of prostatic adenocarcinoma into squamous cell carcinoma after LH-RH agonist intake has been reported in only 8 cases in the literature. To our knowledge, our case is the second pure squamous cell carcinoma observed after hormonotherapy and radiotherapy. We reported a case of a patient with prostatic adenocarcinoma treated by radical prostatectomy followed by radiotherapy. Eleven years later, he had a vesical recurrence of prostatic adenocarcinoma. Our patient had an endoscopic resection followed by injections of Triptorelin. Six months later, he developed a local recurrence of a squamous cell carcinoma.

Paraganglioma is a rare neuroendocrine tumor that arises from the autonomic nervous system. The urinary bladder paraganglioma accounts for less than 0.1% of bladder tumors. It remains a challenging entity to diagnose and treat due to its rareness and the lack of specific symptoms. Treatment modalities include transurethral resection and cystectomy (partial or total). The authors report a new case of an isolated paraganglioma of the urinary bladder in a 52-year-old female patient that underwent partial cystectomy. This case aims to remind the clinical, histological and therapeutic features of this rare tumor.

Human hydatidosis is endemic in regions with temperate climate where pastoral farming is common. It is frequent in the southern shore of the Mediterranean, particularly in the Maghreb countries. It remains asymptomatic for long period, and the diagnosis is often delayed. The most affected organs are the liver and lungs. Hydatic disease of the urinary tract is an unusual entity. Our case concerns multiple unusual locations of hydatic disease in the urinary tract, including renal, retrovesical and spermatic cord, associated with splenic and intraperitoneal locations. Coexistence of hydatic cysts in such locations of urinary tract has not been previously reported.

Introduction: Tubeless percutaneous nephrolithotomy (PCNL) is the non-placement of a nephrostomy tube at the end of the procedure. The benefits of a nephrostomy tube placement are numerous as it provides adequate renal drainage. It may also tamponade bleeding and allow for an easier second-look nephroscopy. However, these advantages are mostly theoretical, and the majority of authors consider the nephrostomy tube as a source of morbidity. Objectives: The aim of this report was to study the efficiency, safety, and morbidity of tubeless PCNL by comparing it to the standard technique. Methods: This is a unicentric retrospective study of 125 patients who had undergone PCNL for renal lithiasis. We divided the patients into two groups: the standard PCNL group (n = 74) and the tubeless PCNL group (n = 51). The rates of good outcomes, complications, duration of hospitalization, and the degree of postoperative pain were compared between these two groups. Results: There were no statistically significant differences between the two groups in age, gender, history, and the number of stones treated. There were more staghorn stones in the PCNL group with nephrostomy (p = 0.007) and more pelvicalyceal stones in the tubeless group (p = 0.037). Patients who had the standard PCNL had larger stones (p = 0.008). Patients who had a tubeless PCNL had more postoperative infectious complications than the standard PCNL group (p = 0.042). No statistically significant differences were noted for other complications, good outcomes (p = 0.13), postoperative pain (p = 0.51), and duration of hospitalization (p = 0.16). Conclusion: According to the majority of authors, tubeless PCNL is considered a safe and efficient technique. It also provides advantages with less postoperative pain and duration of hospitalization. We believe that a selection bias may exist in most published work concerning routine nephrostomy tube placement.
