SUMMARY Introduction: Obstructive nephropathy is a frequent complication in the course of advanced cervical cancer (CC), and ultrasonography-guided percutaneous nephrostomy (PCN) is a well established technique for fast ureteral desobstruction. Objective: To identify possible factors related to the survival and quality of life of patients with advanced CC presenting acute urinary obstructive complications that after desobstruction by PCN recovered urinary flux and renal function. Method: This is an analytical, descriptive, cross-sectional study that included 45 patients with CC who underwent PCN and were divided into 2 groups: “death” (DG) and “survival” (SG), in a public hospital that is reference for oncologic diseases in Northern Brazil. Results: The mean serum creatinine of the patients preceding PCN was >10 mg/dL, and after PCN <2 mg/dL. The cutoffs of 8.7 g/dL for Hb (p=0.0241) and 27% for Ht (p=0.0065) indicated the values that better discriminate the outcomes of the groups. The presence of low blood pressure was statistically correlated (p=0.0037) to the outcome “death”. Changes in glomerular filtration rate (already reduced in all cases) were not associated to the levels of Hb/Ht or to the outcome “death” during the nephrological follow-up. Conclusion: PCN was responsible for the recovery of renal function in 61.7% of the patients, leading to interruption of renal replacement therapy (RRT) in all of those patients. Hb levels >8.7g/dL and Ht >27% were associated to longer survival, and the presence of low blood pressure during follow-up was associated with progression to death.
