Evaluation of the impaction of surgical intervention and its predictive factors in patients with chronic obstructive renal failure.

Abstract

Objective: To evaluate results of surgical intervention in patients with chronic obstructive renal failure with assessment of some of the factors that may predict favorable outcomes. Patients and methods: Eighty-six patients diagnosed clinically with chronic obstructive renal failure (53 men and 33 women ranging in age between 25 and 69 years) included in this study from July 2022 to September 2025. The patients were divided according to history of renal impairment and/or regular dialysis into two groups: Group (A): Patients with no regular dialysis (46 patients) (28 males & 18 females. Group (B): Patients with regular dialysis (40 patients) (25 males & 15 females. All patients have been evaluated according to the protocol of obstructive uropathy preoperatively and followed up for 6 months post operatively. Results: Patients of group A, showed improvement in 33 patients (71.74%), equivocal improvement in7 patients (15.22%) and did not improve in 6 patients (13.04). In patients of group B, renal functions showed different degrees of improvement as follow: In 14 patients (35%) good improvement and subsequent complete weaning from dialysis occurred, while in 16 patients (40%) there was a decrease in weekly dialysis sessions from 3 to 2 sessions/week. In the remaining 10 patients (25%) there was no improvement and patients continued to have regular dialysis as preintervention. The overall complications in this series were (12.79%). The incidence was much more in the chronic cases group B. Conclusion: There is evidence of reversibility of renal function after long standing obstruction which provides justification for efforts to identify and treat urinary tract obstruction even if a patient with an obstruction requires dialysis to avoid the dialysis or kidney transplantation or helping patients under dialysis for complete weaning form dialysis or decrease their number of weekly sessions, and in all cases the risk of the procedures should be weighed against the chances of improvement.
