Study Profile

Design
single-patient case report (26-year-old single male, Razi Hospital, Guilan University of Medical Sciences, Rasht, Iran)
Sample size (n)
1
Intervention
Bilateral leech therapy with two leeches on each side of penile shaft for 2 hours, followed by one-hour break, then another cycle in same manner
Comparator
No control - case report
Primary endpoint
Pain control and resolution of priapism (persistent painful penile erection without sexual stimulation)
Primary result
Significant pain reduction at 2-day follow-up despite persistent cavernosal swelling and tenderness; patient discharged after 3-day admission with complete resolution of pain and perineal swelling over 1 month
Follow-up duration
1 month with complete symptom resolution

Key Findings

  • Priapism resolution with bilateral leech therapy protocol
  • Two leeches per side, 2-hour cycles with 1-hour breaks
  • Significant 2-day pain reduction
  • Complete resolution over 1 month
  • Non-invasive alternative to surgical intervention

Limitations

  • Single case - hypothesis-generating only
  • No mental disorders, trauma, or sickle cell anemia present
  • Cannot quantify leech vs natural history contribution
  • Limited generalizability to common priapism etiologies
  • Off-label use beyond traditional K040187 indications

Clinical Implications

Asgari 2017 introduces hirudotherapy as a non-invasive alternative for refractory priapism management. For US clinicians under K040187, this Iranian case demonstrates extension of device indication to venous-congestion-mediated compartment syndromes outside traditional flap/replant contexts. However, the single-case design and absence of standard etiologies (trauma, sickle cell) limits clinical adoption.
