It is a common observation that following spinal anaesthesia, the penis usually elongates. The aim of this study was to determine the degree of change in penile length following spinal anaesthesia. Consecutive urosurgical patients undergoing spinal anaesthesia were recruited for this study. Those who received general anaesthesia or incomplete spinal blocked were also excluded. The flaccid length of the penis was measured before and after the administration of spinal anaesthesia. Penile length 15 minutes post-spinal anaesthesia was measured and recorded. The change in length was tested for statistical significant difference, the age of patient; diagnosis and type of surgery were also recorded. Forty three patients completed the study. Benign prostatic hypertrophy constituted 41.9% of the surgical indications. While 53.5% of the patients were ASA I, 39.5% and 7.0% of them were ASA II and III respectively. While the mean initial penile length was 12.1 ± 0.53 cm and the mean final length was 15.7 ± 0.53 cm, the mean maximal change in penile length was 3.6±1.5 cm; p<0.0001. There was no statistical correlation between age and mean differential change in length of penis (r= -0.2842, p=0.43). It was therefore concluded that there was a significant change in penile length (tumescence) following successful spinal anaesthesia.
