Predictive value of resistive index, detrusor wall thickness and ultrasound estimated bladder weight regarding the outcome after transurethral prostatectomy for patients with lower urinary tract symptoms suggestive of benign prostatic obstruction
Objectives: To evaluate the value of three parameters from preoperative ultrasonography in predicting the outcome of transurethral prostatectomy in patients with lower urinary tract symptoms suggestive of benign prostatic obstruction. Methods: A total of 239 patients with lower urinary tract sympt...

| description | Objectives: To evaluate the value of three parameters from preoperative ultrasonography in predicting the outcome of transurethral prostatectomy in patients with lower urinary tract symptoms suggestive of benign prostatic obstruction.
Methods: A total of 239 patients with lower urinary tract symptoms suggestive of benign prostatic obstruction entering our department for surgical therapy were prospectively recruited. All of them underwent both ultrasound and urodynamics before receiving standard transurethral prostatectomy by the same team of surgeons. For 202 patients, 6‐month follow‐up data were available after the surgery, including the International Prostate Symptom Score, the Quality of Life score and the maximum flow rate. Preoperative data stratified by different degree of recovery were compared and the influence of ultrasound parameters on the surgical outcome was analyzed by using logistic regression and receiver–operator characteristic curve analyses.
Results: Baseline transitional zone index, intravesical prostatic protrusion, resistive index, detrusor wall thickness and ultrasonic estimation of bladder weight were significantly different between patients with an effective outcome and those with an ineffective outcome (P |

Results: Baseline transitional zone index, intravesical prostatic protrusion, resistive index, detrusor wall thickness and ultrasonic estimation of bladder weight were significantly different between patients with an effective outcome and those with an ineffective outcome (P < 0.05). Resistive index, detrusor wall thickness and ultrasonic estimation of bladder weight were selected as independent factors correlated with the efficacy of transurethral prostatectomy by logistic regression (P < 0.05). All three factors had adequate area under receiver–operator characteristic curve with resistive index having the largest area (0.816, 95% CI 0.759–0.874). The combined positive predictive value in effective surgical outcome of resistive index, detrusor wall thickness and ultrasonic estimation was 96.3%.
Conclusions: Resistive index, detrusor wall thickness and ultrasonic estimation adequately predict the outcome of transurethral prostatectomy. Measuring these parameters by preoperative ultrasound might aid in determining the need for surgical intervention.</description><identifier>ISSN: 0919-8172</identifier><identifier>EISSN: 1442-2042</identifier><identifier>DOI: 10.1111/j.1442-2042.2011.02942.x</identifier><identifier>PMID: 22220830</identifier><language>eng</language><publisher>Melbourne, Australia: Blackwell Publishing Asia</publisher><subject>Aged ; Humans ; Male ; Middle Aged ; Organ Size ; Predictive Value of Tests ; Preoperative Care - methods ; Prospective Studies ; prostatic hyperplasia ; Prostatic Hyperplasia - diagnostic imaging ; Prostatic Hyperplasia - surgery ; transurethral resection of prostate ; Transurethral Resection of Prostate - methods ; Treatment Outcome ; ultrasonography ; Ultrasonography - methods ; Urinary Bladder - diagnostic imaging ; Urinary Bladder - pathology ; Urinary Bladder Neck Obstruction - diagnostic imaging ; Urinary Bladder Neck Obstruction - surgery ; Urinary Bladder, Overactive - diagnostic imaging ; Urinary Bladder, Overactive - surgery ; Urination Disorders - diagnostic imaging ; Urination Disorders - surgery ; urodynamics ; Urodynamics - physiology</subject><ispartof>International journal of urology, 2012-04, Vol.19 (4), p.343-350</ispartof><rights>2012 The Japanese Urological Association</rights><rights>2012 The Japanese Urological Association.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c4592-696f0c9ea7c08c2fcc73566dc9182dab5f942e3b2445f36e140143b3385cd6923</citedby><cites>FETCH-LOGICAL-c4592-696f0c9ea7c08c2fcc73566dc9182dab5f942e3b2445f36e140143b3385cd6923</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27923,27924</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/22220830$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Huang, Tao</creatorcontrib><creatorcontrib>Qi, Jun</creatorcontrib><creatorcontrib>Yu, Yong Jiang</creatorcontrib><creatorcontrib>Xu, Ding</creatorcontrib><creatorcontrib>Jiao, Yang</creatorcontrib><creatorcontrib>Kang, Jian</creatorcontrib><creatorcontrib>Chen, Ya Qin</creatorcontrib><creatorcontrib>Zhu, Yun Kai</creatorcontrib><title>Predictive value of resistive index, detrusor wall thickness and ultrasound estimated bladder weight regarding the outcome after transurethral prostatectomy for patients with lower urinary tract symptoms suggestive of benign prostatic obstruction</title><title>International journal of urology</title><addtitle>Int J Urol</addtitle><description>Objectives: To evaluate the value of three parameters from preoperative ultrasonography in predicting the outcome of transurethral prostatectomy in patients with lower urinary tract symptoms suggestive of benign prostatic obstruction.
