Penile strangulation secondary to utilization of a constrictive ring is a rare urologic emergency that requires urgent decompression to prevent prolonged vascular obstruction resulting in necrosis and gangrene. Current literature is mainly comprised of case presentations that focus on management in the acute setting via removal of the ring. Herein, we describe surgical management of a patient who presents in delayed fashion after self-removal of the constrictive ring. We discuss our penectomy-sparing technique of debridement and split thickness skin graft.

UNASSIGNED: Penile strangulation is a rare urological emergency that necessitates urgent management. The reasoning behind it may include sexual pleasure, erection reinforcement, or a psychiatric disorder.
UNASSIGNED: Despite being an uncommon complication of penile strangulation, we report a 45-year-old prison inmate who presented with penile shaft necrosis secondary to using a non-metallic constriction object. The patient reported a 5-day history of progressive penile pain, edema, and skin injury but no urinary symptoms. The patient underwent complete penile skin degloving, circumcision, and insertion of a suprapubic catheter. Postoperatively, the penile tissue appeared healthy, and the wound was granulating. On the eleventh day following degloving, a full-thickness skin graft was taken from the groin area. The patient remained in the hospital for 20 days, during which he was clinically stable with clean, healing wounds.
UNASSIGNED: Early management of penile strangulation is vital in order to prevent vascular and mechanical complications.

Since 2022 Monkeypox virus (MPXV) infection incidence of cases has increased. Genitourinary lesions and penile edema are one of the main causes of emergency room visits. We aim to describe a 36-year-old man with MPXV infection and newly diagnosed with HIV and low CD4+ count, who developed a rapidly extensive penile necrosis. Extensive surgical debridement was performed and necrosis compromise was confirmed in the histopathological findings. We provide novel forms of presentation of MPXV, improving data collection and awarding health workers for a correct differential diagnosis.

A 72-year-old man on hemodialysis due to diabetic nephropathy presented with a fever and penile pain. Although his physical examination was unremarkable, his general condition deteriorated. Penile necrosis was observed by evening on the same day of presentation, and the patient died the next morning. Blood cultures revealed the presence of Group G Streptococcus, leading to a diagnosis of streptococcal toxic shock syndrome (STSS). Autopsy suggested penile necrosis due to septic shock. STSS in hemodialysis patients with vascular calcification, even in the absence of calciphylaxis, can lead to severe organ damage due to ischemia.

BACKGROUND: Penile calciphylaxis is rarely reported in dialysis patients.
METHODS: We experienced cases of dialysis patients who had penile calciphylaxis between 2003 and 2020.
RESULTS: Seven patients undergoing dialysis were treated for penile necrosis (hemodialysis [HD], 5; peritoneal dialysis [PD], 1; hybrid therapy comprising PD and HD, 1). Their mean age was 62.8 years and their mean dialysis vintage 116.1 months. All had severe penile pain and were clinically diagnosed with calciphylaxis. Four received partial penectomy and three received percutaneous transluminal angioplasty (PTA) due to rapid aggravation. The number of analgesia types and the critical-care pain observation tool score significantly decreased after invasive treatment (both, p = 0.008). The 90-day and 1-year survival rates after onset were 85.7% and 57.1%, respectively.
CONCLUSIONS: In dialysis patients, penile calciphylaxis has poor prognosis; however, invasive treatments for pain management are effective. PTA may be beneficial in dialysis patients in poor condition.

We report a case of leukocytoclastic vasculitis-induced penile necrosis in a 69-year-old male with no previous urologic history. After suffering an ischemic event to the distal shaft of the penis as well as an ischemic event involving the right side of the bladder, he underwent suprapubic tube placement for urinary diversion. Despite attempts at anticoagulation for penile salvage, he lost the distal aspect of the glans penis to auto-necrosis. Ultimately, the underlying disease was determined to be systemic ANCA-associated vasculitis, and the patient was treated with rituximab and prednisone as well as penile wound debridement.

Penile necrosis is an uncommon condition associated, in most cases, with calciphylaxis, also known as calcific uremic arteriolopathy. It is a progressive disease found in approximately 1%-4% of patients with end stage renal disease. Patients with penile calciphylaxis present a mortality rate of up to 70%, with life expectancy of two-and a half months following the diagnosis. We report a severe calciphylaxis case that had to be submitted to a penectomy but survived the penile event.

Circumcision is one of the most frequently performed surgical procedures in the world. Its complication rate is extremely low when performed by a trained surgeon, but the majority of circumcisions done for religious reasons in India, Africa, and Arab states are performed by traditional practitioners1 and have a high complication rate. We present the case of five-year-old boy who developed gangrene of the glans requiring amputation after such a procedure.
