Brief summary

Transurethral resection of the prostate (TURP) is still the gold standard for surgical management of enlarged prostate. However, many techniques and minimally invasive procedures are now in the comparative track with Bipolar resection as Laser enucleation. Multiple drawbacks of Classic TURP problems related to large prostate management as the retreatment after Bipolar resection, another issue that prolonged operative time, Loss of orientation during resection due to rotation of one of the 2 kissing lobe, Bleeding of the 1st lobe resection side make the 2nd lobe resection harder and lengthier, Median lobe resection or bladder neck resection is done at last to avoid sub-trigonal injury. however, due to median lobe obstruction, irrigation is poor during all the resection. length of learning curve, the modification of early median lobe resection carry the risk of sub-trigonal injury. So, this study is a trial to analyze the effect of new technique in resection of large prostate with good orientation and less time of operation.

Interventions

PROCEDURENesbit technique

it is composed of development of trough at the right prostatic lobe (at 10 o'clock) from the bladder neck proximally down to a level just above the external urethral sphincter distally, then deepening the trough until the prostatic capsule, performing haemostasias then resection of lateral lobes in halves, upper right, lower right, upper left and at last lower left respectively with haemostasias in-between. Then resection of the median lobe if present. Final haemostasias then ensues before insertion of the triple way catheter with normal saline irrigation.

PROCEDURECorkscrew technique

the Corkscrew technique was performed by resection starting at 3 o'clock and carried on in a clockwise manner till 3 o'clock again. Prostate was resected from bladder neck downwards to the verumontanum after dividing the gland, imaginary, into 3 zones or thirds, proximal, middle and distal zone. The gland was resected zone by zone in this corkscrew manner. Once the proximal third is resected and hemostasis done, the middle third resection is done in the same manner, The process is repeated for the distal third. Hemostasis was performed instantly.

Design outcomes

Primary

MeasureTime frameDescription
Weight of resected tissuewithin one hour postoperativelyThe weight of resected tissue measured in grams using laboratory scale device.
Resection timethe operative timeResection time measured in minutes by documenting the time of resection start and time of resection end.
Complication ratethe operative timeComplication rate is measured by number of complications occurred.

Secondary

MeasureTime frameDescription
Change in International Prostate symptom score (IPSS)one month postoperativelyThe change in International Prostate Symptom Score (IPSS) is measured by difference between preoperative and postoperative IPSS. IPSS is measured by IPSS scoring system in form of numbers, where minimum score is 0 representing no symptoms and maximum score is 35 representing the most sever symptoms.
Change in hemoglobin levelOne day postoperativelyThe change in hemoglobin is measured by difference between preoperative and postoperative hemoglobin level. Hemoglobin level is assessed using Complete Blood Count and measured by g/dl.
Change in QmaxOne month postoperativelyThe change in IPSS score is measured by difference between preoperative and postoperative Qmax. Qmax (maximum flow rate) is measured using uroflowmetry and measured by ml/sec.
Change in postvoid residual volumeOne month postoperativelyThe change in postvoid residual volume is measured by difference between preoperative and postoperative postvoid residual volume. postvoid residual volume is assessed using pelviabdominal ultrasound and measured by centimeter cubic.
