“…The present study shows that the maximum intravesical pressure, but not the mean pressure or the duration of excessive pressure (>2 kPa), increases when the irrigating fluid bags are placed higher. No increase in fluid absorption occurred when the bags were placed higher, which confirms a previous study on 550 patients undergoing TURP [8]. Nor was there any correla tion between intravesical pressure and fluid absorption.…”

“…This has been taught to urologists since the 1950s, but is based more on logical reasoning than scientific evi dence. We found only a limited effect of bag height on intravesical pressure when the bladder was filled intermit tently [1] and no correlation between bag height and fluid absorption in 550 patients undergoing TURP [3]. The present study confirms that placing the irrigating fluid bag at a certain height between 60 and 95 cm above the oper ating table is neither relevant to the intravesical pressure nor to fluid absorption when the suprapubic trocar is used.…”

“…This height ranged from 60 to 95 cm, measured from the upper surface of the operating table to the middle of the fluid bags, which represents the average fluid pressure during emptying of the bags [3].…”

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.

este estudio fue nuestra intención evaluar la relación entre la reabsorción de líquido de irrigación y tres variables: tiempo de la intervención, volumen de solución de glicina empleado y peso de los fragmentos, durante la RTU de próstata realizada a baja presión hidráulica.Material y método: Estudiamos 74 pacientes a los que se realizó RTU de próstata con derivación suprapúbica con vaina de Amplatz 30 ch. Se monitorizó el etanol en aire expirado cada 15 minutos durante la intervención. Así mismo se anotaron el tiempo de la intervención, el volumen de glicina utilizado y el peso de los fragmentos extraídos. Estadísticamente se utilizó el Test de Anova para comparación de medias.Resultados: Un 13,6 % de los pacientes absorbieron líquido de irrigación en alguna cantidad. El rango de absorción es de 100 cc hasta 2.000 cc. No se encontró una diferencia estadísticamente significativa entre las medias del tiempo de resección, del volumen de glicina y del peso de los fragmentos entre el grupo de pacientes que había reabsorbido líquido de irrigación y los que no reabsorbieron.Conclusiones: Nuestro estudio pone de manifiesto que el tiempo operatorio, el volumen de líquido de irrigación y el peso de los fragmentos resecados no influyen en la reabsorción de líquido de irrigación cuando se realiza una RTU a baja presión hidráulica. ABSTRACT ANALYSIS OF THE ABSORCION´S FACTORS OF IRRIGATING FLUID DURING TRANSURETHRALRESECTION OF THE PROSTATE Objetives: In this study it was our intention to evaluate the relation between the reabsorption of irrigating fluid and three variables: time of the intervention, volume of solution of glicina employee and weight of the fragments, during the RTU of prostate fulfilled to low hydraulic pressure.Material and method: We Study 74 patients that RTU of prostate was performed with suprapúbica derivation with Amplatz's pod 30 ch. The ethanol was monitored in expired air every 15 minutes during the intervention. Likewise we annotated the time of the intervention, the volume of glicina used and the weight of the fragments extracted. Statistically Anova's text was in use for comparison of averages.Results: 13,6 % of the patients absorbed irrigating fluid in some quantity. The range of absorption belongs to 100 cc until 2.000 cc. We did not find a statistically significant difference in the averages of time of resection, volume of glicina and weight of the fragments between the group of patients that had absortion of irrigating fluid and they that didn´t had.Conclusions: Our data show that the operative time, the volume of irrigating fluid and the weight of the resected fragments do not influence the reabsorption of liquid of irrigation when a RTU is realized to low hydraulic pressure.
