PIG-Related Sensory Loss Rare Beyond 1 Year
Loss of penile sensation after plaque incision and grafting surgery declines over time.
ORLANDO—Sensation loss is not uncommon following plaque incision and grafting surgery (PIG) for Peyronie's disease when performed dorsally, but it decreases in frequency and severity over time, researchers concluded in a poster presentation at the American Urological Association 2014 annual meeting.
Raanan Tal, MD, and colleagues at Memorial Sloan-Kettering Cancer Center in New York studied 60 patients who underwent the procedure.
The men had a mean age of 52 years and mean follow-up of 16 months. The mean duration of surgery was 3.5 hours. Patients had in-office follow up at 1 week, 1 month, and 6 months, and were followed up by phone at 12 months or more if problems continued.
Postoperatively, sensory loss was reported by 20% of patients at 1 week, 20% at 1 month, and 7% at 6 months. Two of the 60 patients had sensory loss at 1 year. A single patient at 2 years continued to have extensive sensation loss on the glans and distal shaft, the researchers reported.
The only predictor of sensory loss was duration of surgery, with duration greater than 4 hours predicting sensation loss at 6 months.
“Longer operations are more likely associated with sensation loss, likely related to difficult neurovascular bundle elevation,” the authors wrote.
