Biochemical testing confirmed marked catecholamine hypersecretion, and 18F-FDOPA PET/CT demonstrated isolated uptake within the lesion without additional disease. Preoperative preparation included progressive alpha-adrenergic blockade with doxazosin for approximately 1 month, followed by atenolol for heart rate control. An open approach through a right subcostal hemichevron incision was selected because the tumor was located between the right renal artery and vein and lateral to the inferior vena cava. During dissection, an iatrogenic renal artery injury with intraoperative hemorrhage occurred, necessitating en bloc removal of the tumor, right kidney, and right adrenal gland. Histopathological examination confirmed a paraganglioma with a Ki-67 proliferation index below 1%, focal nuclear atypia, no mitotic figures, no tumor necrosis, no vascular invasion, and microscopic margin involvement.

Recurrent varicocele after previous surgical repair represents an additional challenge in the management of male infertility.

Elevated urinary cystine concentration promotes precipitation and subsequent stone formation, manifesting as recurrent urolithiasis. Cystinuria is the most common genetic condition that results in urolithiasis and is typically diagnosed in adolescence. In this case report, we present a male patient diagnosed with cystinuria at the age of 67. The patient presented with acute left flank pain, and noncontrast CT imaging of the urinary tract identified left renal calculi and multiple proximal ureteric stones, accompanied by hydronephrosis. Ureteroscopy revealed dense calculi resistant to laser fragmentation, and stone analysis confirmed a 100% cystine composition. The patient reported a previous stone event at age 18 with spontaneous passage but had remained stone-free for nearly 50 years and had no prior diagnosis of cystinuria. This case demonstrates that cystinuria, although typically diagnosed in childhood or adolescence, can be diagnosed in older adults with recurrent or resistant urolithiasis. Clinicians should maintain a high index of suspicion for cystinuria in adult patients with unexplained or refractory stone disease, and stone analysis remains essential for accurate diagnosis. Optimal management centres on preventing recurrent stone formation through aggressive fluid intake, dietary modifications and medical alkalinisation of urine.

While immediate surgical repair is associated with superior outcomes compared with conservative management, delayed treatment can lead to significant long-term complications including penile curvature in 30% of cases and erectile dysfunction in 50%-62% of cases. We present the case of a 22-year-old patient who sustained a penile fracture while manipulating his erect penis. Clinical examination revealed penile swelling, bruising, and a 60° leftward curvature. Intraoperative ultrasound (IO-USG) with a linear probe precisely localized a tunica albuginea defect in the right corpus cavernosum, enabling a minimally invasive 1.5-cm transverse incision directly over the fracture site. This approach avoided complete penile degloving, reduced operative time and blood loss, and facilitated complete clot evacuation and defect closure using interrupted 3-0 PDS sutures. Postoperative recovery was uneventful, with the patient discharged the following day and reporting normal erectile function and no penile deformity at the 3-month follow-up. A literature review confirms that while preoperative imaging is commonly utilized for surgical planning, IO-USG guidance for real-time fracture localization and incision placement remains rarely reported. Although MRI and CT offer superior soft tissue resolution, they are limited by availability, time constraints, and radiation exposure. IO-USG is readily accessible and noninvasive; although operator-dependent, it provides high-resolution real-time guidance that enables smaller incisions, minimizes postoperative complications such as glans numbness, and optimizes functional outcomes. We conclude that IO-USG-guided repair of penile fracture facilitates rapid identification of the injury site, accurate assessment of hematoma burden, and targeted surgical approach that avoids penile degloving while ensuring complete repair.</p>","PeriodicalId":30323,"journal":{"name":"Case Reports in Urology","volume":"2026 ","pages":"3418235"},"PeriodicalIF":0.0,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13551490/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148913320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
