The most commonly altered type of Peyronie's disease deformity under oral colchicine treatment is lateral curvature that mostly shifts to the dorsal side.

ABSTRACT

The aim of the present study was to evaluate changes in clinical characteristics of Peyronie's disease (PD) patients under oral colchicine treatment in comparison with the initial clinical evaluation with a special emphasis on patients with altered deformity after treatment. A total of 118 patients under oral treatment with colchicine for at least 3 months in the acute phase of PD were retrospectively evaluated with combined infection and stimulation test. PD patients were followed up in four groups according to the clinical course of the deformity improved, remained unchanged, deteriorated deformities or altered localisation of the deformity. Among 116 patients who completed the treatment, penile curvatures improved in 27.6% (n = 32), remained unchanged in 39.7% (n = 46) and deteriorated in 12.1% (n = 14) of the patients after a follow-up of 8.6 ± 3.2 (6-17) months, while localisation of the deformities changed in 20.7% (n = 24) of the patients. In this group, the initial side of the deformities were lateral, ventral, ventrolateral in 41.6% (n = 10), 29.1% (n = 7) and 8.3% (n = 2) of the patients and of hourglass and notching type (n = 4, 16.6%) respectively. Six (60%) patients with lateral, five (71.4%) with ventral curvatures completed their follow-up period with dorsal curvatures. In conclusion, lateral curvature is the most commonly altered deformity that mostly shifts to the dorsal sise of the penis after colchicine therapy.
