Abstract:
Objective To investigate the efficacy and safety of Solifenacin for the treatment of overactive bladder in children. Methods A retrospective analysis was done in a children admitted to our hospital in January 2010,with lower urinary tract obstruction lead to overactive bladder.The boy was 4 years old,suffering from difficult urinating,urinary frequent,urgency and incontinence for 4 years.Imaging studies (B ultrasound,intravenous urography,CT,bladder voiding urethrography) found bilateral hydronephrosis and kidney collecting system separation with left 3.3 cm and right 2.3 cm in diameter; ureteral dilation with left 1.3 cm,right 1.6 cm in diameter.A transverse septum crossing the urethra at a right angle distal to the verumontanum was detected.According to history,physical examination and imaging examination,a diagnosis for posterior urethral valves was established.Under general anesthesia,urethroscopy found that the valve was attached below urethra wall,divided into two forks towards urethral lateral wall.The valve was excised.Three months later,although good voiding,the hydronephrosis and hydroureter still did not improve.After cystostomy and 6 months follow-up,hydronephrosis and hydroureter still not improved. B ultrasound showed the renal pelvis dilation with left 3.2 cm,right 2.0 cm in diameter,and bilateral ureteral dilation with left 1.3 cm,right 1.4 cm in diameter.Solifenacin (5 mg/tablet),1/3 tablet,about 1.7 mg per day was added. Results After oral Solifenacin one month,hydronephrosis and hydroureter began to improve.After 3 months,hydroureter disappeared; hydronephrosis improved significantly.. B-ultrasound showed the renal collecting system mild dilation with left 1.1 cm,right 1.0 cm in diameter.After 13 months follow-up,no side effects was detected. Conclusions Combined with the surgical treatment,Solifenacin can alleviate hydronephrosis secondary to OAB,and can also protect the renal function.
