An Analysis of Case Logs From American Urologists in the Treatment of Peyronie's Disease.
OBJECTIVE
To review recent trends in the treatment of Peyronie's disease (PD), we assess surgical practice patterns of urologists in the United States with emphasis on specialty training, demographics, and temporal changes.


METHODS
Six-month case log data of American urologists between 2004 and 2013 were obtained from the American Board of Urology. Current Procedural Terminology (CPT) codes were used to identify surgical procedures, including plaque injection.


RESULTS
A total of 6564 urologists were included in the surgical cohort, logging 8195 surgical procedures for PD. Only 15.4% of urologists (1012/6564) reported a surgical case for PD. Andrologists (urologist subspecialty designation) accounted for 5.3% of these urologists (54/1012) and performed 18.5% of PD procedures (P = .0001). The frequency of plaque injections increased from 499 in 2004 to 797 in 2013, a 59% increase, whereas surgical correction remained stable. Urologists performed four times as many injections as surgical procedures for PD (P = .001) with andrologists more likely to attempt injection than surgical correction (P = .045). Among surgeries performed, 73.2% were corrections of angulation without plaque excision, 20.5% were excisions of plaque (with possible grafting) up to 5 cm, and 6.2% were excisions of plaque (with possible grafting) >5 cm. There was a 313% increase in the ratio of plication to plaque manipulation (0.92 in 2004 to 2.91 in 2013).


CONCLUSIONS
PD is treated by a minority of urologists and disproportionately by subspecialist in andrology. When compared with surgical interventions, excluding prosthesis implantation, most surgeons favor conservative treatment. The majority of surgical corrections were corrections of angulation without plaque manipulation.
