Abstract

Background: Malignant tumors outside the urinary tract, such as colorectal cancer, uterine cancer, ovarian cancer, etc. in the late stage develop pressure and invasion of the ureters, causing obstruction of the upper urinary tract, affecting renal function and causing renal failure. Placing a JJ stent via cystoscopy is a less invasive technique that resolves the blockage, ensuring urine flow from the kidneys to the bladder, maintaining normal kidney function. Objectives: To evaluate the efficiency of JJ stent for ureteral blockage due to tumors outside the urinary tract. Patients and methods: The study described 61 patients with upper urinary tract obstruction due to tumors outside the urinary tract and JJ stent insertion indicated at Viet Duc Hospital from 01/2017 to 06/2022. Results:  In 61 patients, the mean age was 58.42 ± 6.36, 100% of the patients had hydronephrosis, in which there were 10 cases of bilateral hydronephrosis. All 71 kidney units of 61 patients with indications for JJ placement were able to be placed, of which: 84.51% were placed through retrograde endoscopy, 6.63% were placed through open surgery when combined with gastroenterology, 7 cases accounting for 9.86% failed upstream placement was carried out downstream under the DSA and were both successful. Evaluation of postoperative results 1 month and 6 months after surgery, no more patients with grade 3 hydronephrosis, the number of grade I and II hydronephrosis also decreased. All cases of creatinine and urea values ​​decreased gradually after surgery 1 months and 6 months returned within normal limits, this improvement was statistically significant with P<0.01. Conclusions: In cases of ureteral obstruction due to malignancies outside the urinary tract, High rate of successful retrograde endoscopic JJ catheter, JJ catheterization helps to reduce hydronephrosis and improve kidney function
