Which one of the following is used as an irrigation solution during transurethral resection of the prostate?
**Core Concept**
The transurethral resection of the prostate (TURP) is a surgical procedure used to treat benign prostatic hyperplasia (BPH), where the prostate gland is removed or reduced in size. The procedure involves the use of an irrigation solution to keep the surgical site clear and prevent damage to surrounding tissues.
**Why the Correct Answer is Right**
The correct irrigation solution used during TURP is glycine, which is a non-electrolytic, non-toxic, and non-irritating solution that helps to prevent fluid overload and electrolyte imbalance. Glycine is also a good lubricant and helps to prevent sticking of the prostate tissue to the resectoscope. It is absorbed into the bloodstream slowly, reducing the risk of fluid overload and other complications.
**Why Each Wrong Option is Incorrect**
**Option A:** Glucose is not typically used as an irrigation solution during TURP due to its potential to cause fluid overload and electrolyte imbalance.
**Option B:** Ringer's lactate is an electrolyte-rich solution that can cause fluid overload and electrolyte imbalances during TURP, making it an inappropriate choice.
**Option C:** Normal saline is an electrolyte-rich solution that can cause fluid overload and electrolyte imbalances during TURP, making it an inappropriate choice.
**Clinical Pearl / High-Yield Fact**
During TURP, it is essential to monitor the patient's fluid balance and electrolyte levels closely to prevent complications such as fluid overload and electrolyte imbalance. Glycine is a safe and effective irrigation solution that can help minimize these risks.
**Correct Answer:** C. Glycine
