[Water-electrolyte homeostasis and hemostasis system after transurethral resection of the prostate]
Abstract:
Changes in coagulogram and water-electrolyte homeostasis were studied in 89 patients surgically treated for prostatic adenoma (TUR). The patients were divided into 2 groups: group 1 (n=21) was operated with use of distilled water, group 2--with 5% glucose solution. The following examinations were made in all the patients: extended coagulogram, total blood count, concentration of electrolytes, creatinin, plasma urea and glucose, osmolality measurements. These were made thrice: before the operation, on postoperative day 1, postoperative day 3. Postoperative changes of hemostasis and water-electrolyte homeostasis of plasma were less significant in group 2. The risk of postoperative hemorrhage is higher in patients of group 1.

Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...

Glomerular Filtration
The first stage in urine formation is glomerular filtration. Each kidney contains approximately 1 million nephrons, the functional units of filtration, with a...
