Intravesical pressure during transurethral resection using Iglesias resectoscope with continuous irrigation and suction.

Intravesical pressure was studied in 20 patients during transurethral resection (TUR) of the prostate using the Iglesias resectoscope with continuous irrigation and suction. The suction pressure (50 cm H20) was considerably lower than that suggested by Iglesias. The amount of irrigant was thereby appreciably diminished and blocking of the outlet system was avoided. The intravesical pressure averaged 35 cm H20 during resection, which is less than in conventional resection, and 15 cm during evacuation of tissue chips. Signs of TUR syndrome were not seen. We consider the new resectoscope to be a considerable improvement for TUR.
