The urological irrigating fluid 1.5% glycine is routinely warmed in specifically designed warming drawers prior to use. This study shows that the use of microwave energy to achieve body temperature in 2-litre bags of glycine solution is biochemically safe and that the sterility of the solution is maintained. There is a linear relationship between the temperature of the solution and time in the microwave oven, so allowing a simple formula to predict the correct heating time given variable ambient starting temperatures.

We present 56 patients with urethral calculi. In males the commonest location was the posterior urethra; 46 patients complained of dysuria but urinary retention was present in only 7. ⋯ Transurethral litholapaxy or lithotripsy after retrograde manipulation was performed in 33 patients. Endoscopic manipulation was found to be the safest procedure.
