Abstract

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.
