Outcomes after laser enucleation of the prostate with and without significant storage symptoms.

Abstract

Objective: To test for differences in recovery of lower urinary tract symptoms (LUTS) between patients with storage-positive vs -negative symptoms after laser enucleation of the prostate (LEP).

Patients and methods: Consecutive storage-positive (severe storage symptoms, International Prostate Symptom Score [IPSS] storage subscore >8) vs storage-negative patients treated with LEP (November 2017-September 2022) within our tertiary-care database were identified. Mixed linear models tested for changes in IPSS and quality of life (QoL) at 1, 3 and 12 months after LEP. Multiple linear regression models tested for LUTS and QoL recovery risk factors at 1, 3 and 12 months.

Results: Of 291 study patients, 180 (62%) had storage-positive symptoms. There were no differences between storage-positive and -negative patients in mean adjusted total IPSS, IPSS-storage, IPSS-voiding and QoL at 12 months after LEP. In multiple linear regression models, storage-positive status was identified as a risk factor for higher IPSS at 1 month (β coefficient 2.98, P = 0.004) and 3 months (β coefficient 2.24, P = 0.04), as well as for more unfavourable QoL at 1 month (β coefficient 0.74, P = 0.006) and 3 months (β coefficient 0.73, P = 0.004) after LEP. Conversely, at 12 months there were no differences between storage-positive vs -negative patients.

Conclusion: Storage-positive patients appear to experience similar long-term benefits from LEP compared to storage-negative patients. However, significant storage symptoms are associated with higher total IPSS and less favourable QoL at 1 and 3 months after LEP. These findings advocate for the consideration of LEP also in storage-positive cases with the need for thorough patient education especially in the initial post-LEP period.
