the effect of modified turp (m-turp) in intra and postoperative complications

background transurethral resection of the prostate (turp) is the most common surgical treatment for benign prostatic hyperplasia. objectives the aim of the present study was to compare the conventional bipolar transurethral resection of prostate (turp) with a modified transurethral resection of the prostate (m-turp) in men with mild to moderate symptoms of benign prostatic hyperplasia. patients and methods to compare and evaluate the clinical outcomes of m-turp, a new electrosurgical suggested method, with the standard treatment, transurethral resection of prostate (turp), 200 patients with benign prostatic enlargement causing moderate to severe clinical lower urinary symptoms were selected and divided into two equal groups of a and b. patients of group a underwent m-turp (incomplete bladder neck resection), resecting only from 1 to 11 o&apos;clock position and group b underwent conventional turp. these patients were evaluated between jun 2008 and april 2011, after excluding 24 patients, finally 176 men were studied, 98 in the conventional monopolar transurethral resection of prostate (turp) group and 78 in the (m-turp) group. postoperative follow up to assess the results of the surgeries and the complication rates, began from the operation and continued with postoperative visits of the patient at 24 hour after the catheter remove, two weeks, three months and finally six months. results the age range of both groups were the same (65-82 years old), preoperative ipss score in study and control groups were 18 ± 3.3, 17 ± 4.6 (nonsignificant p value = ns) respectively. the size of prostate gland was 58 ± 3.5 g in study and 78 ± 1.2 g in control (ns) preoperatively. intra and postoperative complications including hematuria (need for transfusion), urine retention (need for catheterization), fever after operation in study and control groups were 2.04%, 6.41%, 1.02% and 0.0%, 3.06%, 6.41% respectively. isi score (stress incontinence score index) were 7 ± 2.5 and 19 ± 3.6 and ur (urge ratio) were %26 and %70 for study and control groups respectively; p < 0.05. iief (international index of erectile function) in study group was better than control (23 ± 3.2 vs. 11 ± 1.7), p < 0.05. conclusions the results of this study showed that the support of anterior fibro muscular zone (anterior lobe) of prostate after tur-p has a significant role in postoperative complications, especially in postoperative stress incontinence. so, we strongly recommend to preserve this segment of prostate for prevention of incontinence and other intra and postoperative complications.
