Summary
Penile strangulation requires prompt treatment to avoid tissue damage. A modified string method with needle decompression safely removed a constricting ring, avoiding surgery.
Area of Science:
- Urology
- Emergency Medicine
- Sexual Health
Background:
- Penile strangulation is a rare but serious urological emergency.
- Delayed treatment can lead to ischemia, gangrene, and potential loss of penile tissue.
- Constriction devices, often used for sexual stimulation, can cause severe penile swelling.
Purpose of the Study:
- To report a case of penile strangulation due to a metallic ring.
- To describe a minimally invasive technique for device removal.
- To evaluate the safety and efficacy of the modified string method.
Main Methods:
- A 52-year-old male presented with a 36-hour history of penile strangulation from a metallic ring.
- Initial manual removal attempts failed due to severe edema.
- A modified string method combined with needle puncture for decompression was employed.
Main Results:
- The modified string method successfully reduced penile volume.
- The metallic ring was safely removed without complications.
- The patient avoided surgical intervention.
- No evidence of penile necrosis was observed.
Conclusions:
- The modified string method is a safe and effective technique for managing penile strangulation caused by rigid devices.
- This minimally invasive approach is particularly useful for low-grade strangulation cases.
- Prompt intervention with appropriate techniques can prevent severe complications.
