“…The present study confirms that low-degree absorption is associated with a slightly higher intravesical pressure than operations or periods of surgery without absorption [6,14], However, massive absorption is not associated No interaction between bag height and bladder capacity was found. 3 ( 1 +log absorption) was used to allow for skewness.…”

We studied whether the height of the irrigating fluid bags above the operating table and the capacity of the bladder influence intravesical pressure and fluid absorption during transurethral resection of the prostate (TURP) when evacuation is performed with Reuter’s trocar. For this purpose, the intravesical pressure was recorded continuously, and the fluid absorption was measured by the ethanol method during 30 TURP procedures. The bags were placed between 60 and 95 cm above the operating table, and the bladder capacity was measured before surgery started. The results show that the bladder capacity, but not the bag height, correlated with the intravesical pressure and the fluid absorption. Large-sized bladders were associated with lower pressures and smaller absorption. Rapid absorption ( > 30 ml/min) occurred at a maximum pressure of 2–3 kPa and a mean pressure of between 1 and 2 kPa. In conclusion, the size of the bladder is important to the intravesical pressure and to the fluid absorption during TURP when using the suprapubic trocar.

“…Instead, it occurs typical ly at a maximum pressure of between 2 and 3 kPa and a mean pressure of between 1 and 2 kPa [1,6,14], These pressures were frequently surpassed in our study which explains why fluid absorption was common.…”

“…extravascular absorption is even lower [6,7], However, there seems to be practically no information concerning another key factor in the possible relationship between bag height and fluid absorption, e.g. the intravesical pres sure that actually results from placing the fluid bag at a particular height above the operating table.…”

“…From continuous recordings of the intravesical pressure in a previous series of 37 TURPs, five operations were selected in which absorption of between 1,146 and 1,911 ml of irri gating fluid had occurred over 20-50 min [10]. The lluid absorption had been measured volumetrically every 10 min with the aid of a 'regular-interval' monitoring programme.…”

The use of irrigating fluid containing a small amount of ethanol allows fluid absorption to be monitored by means of expired-breath tests during transurethral resection of the prostate (TURP). There is, however, no consensus concerning how the breath ethanol data should be converted into the volume of irrigant absorbed. The present study examines the use of the product of concentration and time (area under the curve) to predict how much fluid is absorbed. Intermittent infusions of ethanol in 5 volunteers showed that the relationship between area under the curve and ethanol load was best described by a polynomial expression. This was also applicable to the uptake of small volumes of irrigating fluid during 16 TURPs. When patients with large-sized absorption ( > 1,000 ml) were also considered, however, the precision was better when the absorbed volume was predicted by a multiple linear regression formula where the ethanol level in the exhaled breath at the end of any 10-min period during TURP and the time during which ethanol had been detected served as independent factors.
