Drug treatment of bothersome lower urinary tract symptoms after ureteric JJ-stent insertion: A contemporary, comparative, prospective, randomised placebo-controlled study, single-centre experience

Abstract

Objective

To provide a guide for medication to alleviate bothersome lower urinary tract symptoms (LUTS) in patients after JJ ureteric stenting.

Patients and methods

Between June 2011 and June 2015, a prospective randomised placebo-controlled study was conducted on 200 consecutive cases of ureteric stones that required JJ stents. All patients had signed informed consent and JJ-stent placement confirmed by X-ray. The patients were randomised into five groups: A, solifenacin 5 mg; B, trospium chloride 20 mg; C, antispasmodic; and E, α-blocker; and a placebo group (D). A standard model was created to lessen patient selection bias. Eligible patients were enrolled and assessed for side-effects and bothersome LUTS using the validated Ureteric Stent Symptoms Questionnaire. Appropriate statistical analysis was carried out.

Results

In all, 150 male patients in the five groups were compared. LUTS were less in groups A and B ( P < 0.05), while dry mouth was significantly reported in Group A. Individual comparisons with the placebo group showed a non-significant difference with Group C, while Group E had significant nocturia improvement. Selective comparison of two best groups (A and B) showed less frequency in Group B, while the other LUTS were less in Group A with comparable side-effects.

Conclusions

In symptomatic patients following JJ-stent insertion, anti-muscarinic medication, namely solifenacin 5 mg or trospium chloride 20 mg, was the best. The advantage of trospium over solifenacin is in the control of frequency rather than the other symptoms. Addition of an α-blocker (alfuzosin 10 mg) is valuable when nocturia is the predominant symptom.
