Abstract:
Objective To evaluate the efficacy and technique of minimally invasive management for acute ureteral obstruction and severe infection caused by calculi.Methods A total of 51 patients with acute upper urinary tract obstruction and severe infection caused by calculi were enrolled in this study.When infection,sepsis,and electrolyte disorders were corrected,emergent drainage by retrograde ureteral catheterization using cystoscopy or B-ultrasonography-guided percutaneous nephrostomy were carried out.Ureteroscopic lithotripsy or extracorporeal shock wave lithotripsy(ESWL)were performed after the infection was controlled.Results Cystoscopic retrograde ureteral catheterization was completed in 8 cases,and the other 43 patients were treated successfully by B-ultrasonography-guided percutaneous nephrostomy.During the operations,purulent urine spurted out from the drainage tube.Ten patients had transient hematuria and lumbar pain postoperation.None of the patients developed pneumothorax,urinary extravasation,perirenal hematoma,or abdominal organ injuries,etc.In 3 cases,recauterization was done because the catheter dropped out.In all the patients,the body temperature and blood white blood cell counts returned to a normal range 3 to 7 days after the drainage.Among the cases,8 were treated with ESWL,35 received ureteroscopic lithotripsy,and 8 underwent ESWL after the ureteral stone being pushed upwards to the renal pelvis.No severe complications,such as ureteral perforation or tears,massive hemorrhage,or high fever occurred after lithotripsy.The stones were completely removed in all the cases in 3 weeks postoperation(in 1 week for 34 cases).The patients were followed up for 3 to 6 months,during which the renal function recovered to a normal level.Conclusions Retrograde ureteral catheterization using cystoscopy or B-ultrasonography-guided percutaneous nephrostomy combined with ureteroscopic lithotripsy or ESWL is efficient for patients with acute ureteral obstruction and severe infection caused by calculi.By using the method,ureteral infection can be controlled quickly without causing severe complications.
