Introduction. Simultaneous procedures, provided that each aspect is sufficiently developed, can be an ideal treatment option for concomitant surgical diseases, including kidney and urinary tract. However, at present, they are performed only in 1.5–6.0% of patients who require such interventions.
Aim: The comparative study of the perioperative results of simultaneous procedures and the corresponding isolated interventions on the genitourinary organs was performed. An operative time (min), blood loss volume (ml), catheterization time (min), the frequency of infectious and inflammatory complications of genitourinary organs in the early postoperative period (%), postoperative length of stay, the duration of the anesthesia induction and the period of awakening (in case of endotracheal anesthesia) were analyzed.
Materials and methods. A retrospective analysis of the perioperative results of 5748 patients who were treated in the St. Petersburg State Budgetary Institution of Health Clinical Hospital of St. Luke was carried out.
Results. The advantages of simultaneous procedures over two- and multistage urological interventions in terms of the operative time, the volume of intraoperative blood loss, the frequency of infectious and inflammatory complications from the urogenital system in the early postoperative period, and other studied indicators were revealed.
Conclusion. The results of the study fully confirm the feasibility, legitimacy and need for wider use of simultaneous procedures for the elective treatment of combined urologic diseases.
