Absorption of irrigating fluid during percutaneous transrenal lithotripsy.

Twenty-eight patients who underwent percutaneous lithotripsy with isotonic mannitol solution as the irrigating fluid were studied. Intraoperative intravenous and total absorption of irrigating fluid was estimated from postoperative analyses of plasma and urinary concentrations of mannitol. Most operating times were short and only minor fluid absorption was recorded.

A comparison between intermittent and continuous transurethral resection of the prostate.

123 transurethral resections of the prostate were studied. The operations were randomized to either continuous or intermittent technique. The first 64 operations were performed using an irrigating fluid pressure head of 65 cm (measured from the top of the operating table).

A comparison between two hypotonic irrigating solutions used in transurethral resections of the prostate: sorbitol (2%)-mannitol (1%) and 1.5% glycine solutions.

Two hypotonic but non-haemolysing irrigating solutions, sorbitol-mannitol (2% + 1%) and glycine (1.5%), were compared in 40 TURP cases using a continuous resection technique. Ethanol (1%) was added to the irrigating fluid as a marker to make possible early detection of fluid absorption by breath analysis.

Water and electrolytes in muscle tissue and free amino acids in muscle and plasma in connection with transurethral resection of the prostate. II. Isotonic 2.2% glycine solution as an irrigating fluid.

Seventeen patients undergoing transurethral resection of the prostate using isotonic 2.2% glycine solution as an irrigating fluid were studied. The extra- and intracellular distribution of water, the total content of water, and the concentrations of electrolytes and free amino acids in muscle tissue were determined together with the concentrations of free amino acids in plasma preoperatively, immediately postoperatively and 2, 6, 24 and 48 hours postoperatively in two groups with separate sampling periods.
