Treatment modalities for small-sized urolithiases and their impact on health-related quality of life.

INTRODUCTION Health-related quality of life (HRQoL) is often reduced in patients with urolithiasis. The objective of this study was to perform a systematic review to describe impact on HRQoL based on different modalities of treatment for small urolithiases with a diameter smaller or equal to 10 mm. METHODS Electronic databases were searched with no language or date restrictions to identify studies which were included if they reported: adult patients (≥18 years old), renal or ureteral stone(s) confirmed on imagery, validated reporting of HRQoL, and stone diameter equal or smaller than 10 mm undergoing active surveillance, medical expulsive therapy (MET), shockwave lithotripsy (SWL), or ureteroscopy (URS). RESULTS Of 672 citations, nine articles were eligible. Five studies (all ureteral) reported HRQoL according to medical stone management. Three of them found that HRQoL in MET patients was better than in active surveillance patients and two studies found no difference in HRQoL between MET and active surveillance groups. Four studies (three ureteral, one renal) reported HRQoL according to surgical stone management. Of the ureteral stone studies, two reported better HRQoL in URS patients than in SWL patients, while one study found no difference between URS and SWL groups. In the renal stone study, SWL patients had better HRQoL than URS patients. CONCLUSIONS Patients with urinary stones 10 mm or smaller have better HRQoL when treated with MET vs. active surveillance, when treated with SWL vs. URS for renal stones, and when treated with URS vs. SWL for ureteral stones. There is an important need for more studies on this topic.
