Usefulness of Endovascular Therapy for Penile Gangrene Secondary to Calciphylaxis: A Case Report

Risk factors, treatment modalities, and clinical outcomes of penile calciphylaxis: systematic review

PURPOSE

To perform a systematic review of case reports and case series to investigate risk factors, treatment modalities, and the outcome of penile calciphylaxis.

METHOD

We performed a systematic search of the MEDLINE and Scopus databases to identify case reports or case series of penile calciphylaxis. The patient characteristics, laboratory investigations, diagnostic modalities, treatment modalities, and outcomes were extracted. We compared clinical characteristics and treatment between patients who survived or demised and between patients with clinical improvement and those without to identify the poor prognostic risk factors.

RESULTS

Ninety-four articles were included from 86 case reports and 8 case series with 121 patients. Most of the patients were on hemodialysis (78.9%). The median time since starting dialysis was 48 months (24-96 months). Sodium thiosulfate was used to treat penile calciphylaxis in 23.6%. For surgical management, partial or total penectomy was performed in 45.5% of the patients. There was no association between sodium thiosulfate use, partial or total penectomy, and improvement in clinical outcomes. The mortality rate in patients with penile calciphylaxis was 47.8% and the median time to death was 3 months (0.75-9 months). The presence of extragenital involvement was significantly related to mortality (p = 0.03).

CONCLUSION

A calcified penile artery results in penile calciphylaxis, a rare vascular phenomenon associated with high morbidity and mortality. Management of penile calciphylaxis includes the medical management of risk factors, surgical debridement, or penectomy. Therefore, early prevention and diagnosis as well as immediate appropriate treatment are needed.

Penile calciphylaxis-a complicated case managed with circumcision and glansectomy

Penile calciphylaxis is a serious manifestation of calcifying uremic arteriolopathy, with only a small number of cases reported in the literature. It is rare, characterized by calcification within the walls of small vessels, resulting in ischaemic changes to the skin, and is mainly seen in patients with end-stage renal failure (ESRF). Management of penile calciphylaxis is difficult, with both conservative and surgical approaches advocated for. Due to their comorbidity profile, patients with penile calciphylaxis can present multiple management challenges. We present a case of penile calciphylaxis in a patient with ESRF who was initially managed conservatively, and then underwent circumcision and glansectomy due to a necrotic glans penis and non-resolving penile pain. The patient was spared a partial penectomy and went on to make a full recovery.

Penile calciphylaxis in patients with end-stage kidney disease undergoing dialysis: invasive treatment and pain management

INTRODUCTION

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.

CONCLUSION

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. This article is protected by copyright. All rights reserved.

Internal Pudendal Artery Angioplasty to Rescue Penile Gangrene

Internal pudendal artery (IPA) is a branch of internal iliac artery that mainly supplies the perineal organs and external genitalia. Any obstruction in the artery seen in diabetics, hypertensives, or chronic kidney disease-induced calciphylaxis leads to decreased blood flow and may cause gangrene. IPA angioplasty is a known therapeutic procedure for erectile dysfunction and has shown promising results. However, similar procedure to relieve arterial blockade may be used to stop spread of penile gangrene and save the anatomical and physiological functions of the penis. We report a novel case of IPA angioplasty in patient of penile gangrene to circumvent total penectomy.

Penile calciphylaxis with extragenital gangrene

Penile calciphylaxis is a rare cause of penile gangrene and is typically associated with multiple comorbidities, most commonly diabetes mellitus and hyperparathyroidism. It demonstrates a high mortality rate of 64% and is seen almost exclusively in patients with end-stage renal disease on hemodialysis. Underreporting of this disease likely occurs, contributing to a paucity of data and lack of formal therapeutic guidelines and approved treatments. Conflicting guidance exists regarding effective treatment strategies, with most formal literature existing in the form of case reports. Herein, we describe a 44-year-old man with end-stage renal disease on hemodialysis who presented with a 2-month history of nonhealing wounds on his penis and lower extremities.

Penile necrosis by calciphylaxis leading to gangrene in a patient with chronic renal failure on dialysis: A case report

•

Penile necrosis by calciphylaxis is a rare disease.

•

The diagnosis of CUA is often difficult.

•

The Management of this rare condition is still a matter of debate.

Introduction

Penile calciphylaxis is a rare disease whose diagnosis is not easy. It is associated with chronic renal failure. It is a result of media calcification and blood vessels’ fibrosis such as penile arteries that eventually lead to gangrene formation in extremities and penis. Calcific uremic arteriolopathy is commonly associated with secondary hyperparathyroidism and high level of calcium and phosphate.

Presentation of case

In this paper, we report a case of penile necrosis induced by calciphylaxis associated with chronic renal failure and diabetic macroangiopathy. We performed a partial and total amputation in two stages because of the wound infection. The patient died one week after a total penectomy.

Discussion

The skin biopsy is the gold standard for the diagnosis despite being a risky process. In most cases, appropriate medical management is advocated. The treatment of this pathology is still controversial.

Conclusion

The management of this rare situation is controversial, and its diagnosis is still difficult due to the scarcity of reported cases.

Penile gangrene due to calciphylaxis: a multidisciplinary approach to a complex clinical challenge

Penile calciphylaxis is a rare but clinically challenging condition to manage. While multiple treatment options have been proposed, the underlying evidence is anecdotal, and the overall prognosis remains extremely poor. We describe the case of a patient who underwent urgent debridement of a suspected gangrenous penile tip, who was intraoperatively found to have penile calciphylaxis. The necrosis progressed and the patient had a glans amputation. A non-healing wound developed, requiring reconstruction with two skin grafts using foreskin by the plastic and reconstructive surgical unit. The patient was commenced on sodium thiosulfate and his wound had completely healed 2 months following his last operation. We review the literature to determine the biochemical features, management options and outcomes in patients with penile calciphylaxis.

Management of Penile Calciphylaxis: A Case Study

BACKGROUND

Calciphylaxis, also called calcific uremic arteriolopathy, is a highly morbid syndrome characterized by calcium deposition and occlusion of small arterial vessels of the dermis and subdermal adipose tissue, leading to necrosis and gangrene. Penile involvement is rare and its management presents considerable challenges.

CASE

We review the case of a 47-year-old man with end-stage renal disease managed with hemodialysis, diabetes mellitus, and urinary incontinence who presented with a painful necrotic lesion on his glans penis, and the second and third toes of his right foot. Following diagnosis of calciphylaxis of the toes and penis, he was conservatively managed with topical wound care, sodium thiosulfate adjustment of hemodialysis, and phosphate binder medications. Over the course of 2 months, his wound worsened in the setting of continued urinary incontinence, and before planned diversion with a suprapubic catheter, he progressed to gangrene and sepsis. After a goals-of-care discussion with the patient and family, he elected to forego debridement and was discharged on home-based palliative care.

CONCLUSIONS

Penile calciphylaxis is a rare, life-threatening disease that portends a poor prognosis. Conservative principles for management include normalization of calcium phosphate levels and local wound care. Penectomy may not impact survival. Ultimately, each case is individualized, and we encourage establishing goals of care in collaborative discussion with an interdisciplinary care team, patient, and family.

Penile Calciphylaxis in a Patient with End-stage Renal Disease: A Case Report and Review of the Literature

Penile calciphylaxis is a rare cause of penile gangrene that presents in patients with end-stage renal disease. The rates of comorbidity and mortality of penile calciphylaxis are extremely high. Unlike other penile gangrene, such as Fournier's gangrene, the benefit of aggressive surgical therapy is controversial. Here we present a case of penile calciphylaxis in a 43-year-old man with end-stage renal disease on hemodialysis. He received total penectomy but died due to multisystem complications 2 weeks after surgery. We review the literature on the management options and outcomes in patients with penile calciphylaxis.
