Long-term Results of Organ-preserving Surgeries for Removal of Cystic Kidney Tumors of Category III-VI According to Bosniak
Keywords:organ-saving operations, cystic kidney tumors, long-term results
The objective: to study the long-term results of organ-preserving surgeries when removing cystic kidney tumors of category III – VI according to Bosniak.
Materials and methods. The study was carried out with the participation of 16 patients with verified cystic renal tumors of the category III – VI according to Bosniak. Indications for surgery were: clinical manifestations, laboratory, ultrasound, Doppler and radiation methods (MSCT with bolus contrast or MRI). The diagnosis of renal tumor process was also confirmed using histological and histochemical research methods.
Results. Long-term studies after 18 and 36 months showed no signs of recurrence of cysts or tumor process in the kidneys. Signs of a tumor process in the lymph nodes or in other organs during these periods of the study were also not found. Removal of cysts and tumors in the long term after surgery leads to a significant improvement in blood circulation in the kidneys.Conclusion. Organ-preserving resection of a part of the kidney affected by Bosniak category III–VI cystic tumors is a modern effective method of treatment and should be an alternative to surgical removal of affected kidneys in such patients.
