Introduction :
Self-retaining ureteral stents are commonly used to relieve or prevent obstruction of the upper urinary tract after urinary stone surgery. However, they are associated with a variety of symptoms of which urinary symptoms constitute a major part. Patient need to keep the stent insitu for four to six weeks because traditional ureteral stents require cystoscopic removal by urologist which is limited by waiting time and cystoscopy session. The new magnetic double J stent allows removal in day ward setting which can perform by urology nurse. As a result, a nurse-led double J stent removal service was set up in August 2018 to provide early stent removal service for these patients.
Objectives :
To evaluate the efficacy of this new device and service with regard to its applicability, safety and side effects.
Methodology :
Patients with conventional double J stent and new magnetic double J stent inserted after ureteroscopic lithotripsy (URSL) between Jan 2019 to Sept 2019 were recruited. Patient demographics, stent irrivative symptoms and time to stent removal were analysed retrospectively.
Result & Outcome :
A total of sixty patients (30 with magnetic double J stent & 30 with conventional double J stent) were recruited. There was no significance difference for patient demographics with median age: 55.3 (Magnetic J) & 58.2 (Conventional J) (P>0.05). However, significance difference was found regarding the median waiting time to stent removal was 8 days in magnetic J group & 35 days in conventional J group (P< 0.05) & the median time for stent removal in endoscopy unit was 6 mins for conventional stent and 2 mins for stent removal in nurse clinic for magnetic stent. (P< 0.05). In addition, the median visual analogue score (VAS) for magnetic stent removal was 3.3 and 4.4 for conventional removal (P< 0.05) and the International prostate symptoms score (IPSS) showed statistically significant difference between 2 groups 3.2 (Magnetic J) v.s. 8.7 (Conventional J) (P< 0.05)
