Abstract
Relevance. Chronic renal failure in patients undergoing radical cystoprostatectomy (RCPE) with various variants of urine derivation is one of the significant problems that requires an interdisciplinary approach. To date, there is an insufficient number of studies comparing a significant decrease in glomerular filtration rate (GFR) between different types of urine diversion after radical cystectomy.
Purpose of research. To study glomerular filtration rate (GFR) indicators in patients who underwent radical cystectomy with a heterotopic Bricker reservoir and compare them with similar indicators in patients who underwent radical cystectomy with a « V « shaped heterotopic reservoir. To compare early postoperative complications in patients who underwent radical cystoprostatectomy with the formation of a heterotopic Bricker reservoir and with a modified V-shaped heterotopic reservoir.
Materials and methods. To study and compare the dynamics of glomerular filtration rate (GFR), we retrospectively selected patients after radical cystoprostatectomy with heterotypic ileocystoplasty. Patients were divided into two groups: the control group — patients with radical cystoprostatectomy and Bricker ileocystoplasty (n=46), the study group — patients with radical cystoprostatectomy and modified V-shaped heterotopic ileocystoplasty (n=49).
Results. At the stage of discharge of patients from the hospital after radical cystoprostatectomy, the level of glomerular filtration rate (GFR) was not statistically significant differences between the study and control group (P=0.3791), including patients with the presence of hydronephrosis (P=0.4664).
The difference in glomerular filtration rate (GFR) between the study group and the control group was statistically significant after 6 years of dynamic follow-up. As a result, it can be argued that the dynamics of glomerular filtration rate (GFR) reduction in the study group is lower than in the control group. A particularly significant difference in glomerular filtration rate (GFR) was observed in patients with existing hydronephrosis at the preoperative stage.
Conclusion. Modified «V» — shaped heterotopic urine derivation can be recommended for patients who have undergone radical cystoprostatectomy, especially with existing hydronephrosis at the preoperative stage.
This method should be used in patients with chronic pyelonephritis against the background of previously diagnosed ureterohydronephrosis, which is a fairly frequent consequence of the invasive nature of the growth of bladder cancer with ureteral obstruction.
