Abstract:
Objective:To evaluated the subcutaneous nephrovesical bypass carried out in patients with ureter obstruction and improve the quality of life of patients with palliative definitive percutaneous nephrostomy.Methods:A total of 36 patients with advanced cancer receiving 45 subcutaneous nephrovesical bypass tubes were included in the study.Uronephrosis ranged from 1.8-5.2 cm,serum creatinine 73-760 ?mol/L,and glomerular filtration rate(GFR) 19-26 mL/min.The obstruction was proved to be complete by retrograde pyelography.The nephrovesical stents were inserted utilizing percutaneous access to both of the kidney and bladder,and a subcutaneous tunnel was created between the two sites.B-ultrasound,KUB(kidneys,ureters,and bladder),serum creatinine test and GFR were carried out 72 hours after operation.Results:Urinary diversion operations were successful in the 36 patients,uronephrosis ranged from 0-1.8 cm,all stents were in position,serum creatinine 72-173 ?mol/L,GFR 25-40 mL/min after the operation,and the bypass functioned well in 45 stents for 67 to 481 days of the follow-up.Conclusion:Subcutaneous nephrovesical bypass can protect renal function of patients suffering from ureteral obstruction by simple and minimum invasive operation;it can also reduce complications caused by percutaneous nephrostomy and improve the patient's life quality.
