Several key risk factors contribute to the likelihood of developing Transurethral resection of the prostate (TURP) syndrome. One of the most significant is the duration of the surgery. The longer the procedure, the higher the risk of fluid absorption, with most absorption occurring after the first 30 minutes. Another critical factor is the volume and pressure of the irrigating fluid used during the procedure. High hydrostatic pressure increases the likelihood of the fluid being absorbed into the bloodstream, especially if large venous sinuses are opened during resection. Larger prostate sizes also pose a higher risk since they require more extensive resection, prolonging surgery and increasing exposure to large volumes of irrigating fluid.
Additionally, the number and size of venous sinuses opened during the procedure significantly impact fluid absorption rates. Larger sinuses allow more fluid to enter the circulatory system, heightening the risk of TURP syndrome. The surgeon's experience also plays a crucial role; more experienced surgeons can often reduce the duration of surgery and control venous bleeding more effectively, minimizing fluid absorption. Understanding these risk factors is essential for both urologists and anesthesia providers in planning and managing TURP procedures to prevent the onset of TURP syndrome.
| Risk factor | Why absorption increases |
|---|---|
| Duration of surgery | Longer procedures absorb more fluid, with most absorption occurring after the first 30 minutes |
| Irrigation volume and pressure | High hydrostatic pressure drives fluid into the bloodstream, particularly when large venous sinuses are open |
| Prostate size | Larger glands require more extensive resection, prolonging surgery and exposure to irrigant |
| Venous sinuses opened | More and larger sinuses allow more fluid to enter the circulation |
| Surgeon experience | Experienced surgeons shorten operating time and control venous bleeding more effectively |
