“…Interest has therefore arisen in the development of noninvasive methods for assessing lower urinary tract function. The diagnostic potential of measurements of BWT, detrusor wall thickness, and US-estimated bladder weight in men with LUTS and various degrees of BOO have been explored [5,11-14]. …”

PurposeBladder wall thickness (BWT) is reported to be related to detrusor overactivity and bladder outlet obstruction. We investigated the relationship between BWT and the responsiveness of storage symptoms to alpha-blockers in men with lower urinary tract symptoms (LUTS).Materials and MethodsA total of 74 patients with LUTS were enrolled. International Prostate Symptom Score, uroflowmetry with post-void residual urine volume, and transrectal ultrasonography (TRUS) were investigated. BWT was measured by performing TRUS at the midsagittal plane view, and the average value of BWT at the anterior, dome, and trigone areas was used. After 4 weeks of alpha-blocker medication, patients were reevaluated and divided into two groups. The responder group consisted of patients who reported improvement in the storage symptom subscore of 2 points or more; the non-responder group consisted of patients who reported improvement of less than 2 points. Clinical parameters including BWT were compared between the two groups.ResultsA total of 52 patients were followed. BWT was positively correlated with intravesical prostate protrusion (IPP) (9.26±4.99, standardized beta=0.393, p=0.002) and storage symptom subscore (0.35±0.43, standardized beta=0.458, p=0.002). Compared with that in the responder group, BWT was thicker in the non-responder group, and improvement in the storage symptom score was correlated with BWT (0.58±0.09 cm vs. 0.65±0.11 cm, p=0.018) and prostate volume (27.08±16.26 ml vs. 36.44±10.1 ml, p=0.018).ConclusionsBWT was correlated with IPP, the storage symptom subscore, and the responsiveness of storage symptoms to alpha-blockers in LUTS/benign prostatic hyperplasia (BPH) patients. As BWT increased, the responsiveness of storage symptoms to alpha-blocker decreased in LUTS/BPH patients.

“…The concept of bladder weight (BW) as a measure of bladder wall hypertrophy has also been introduced [85]. Comparison of UEBW and PFS revealed that UEBW could identify BOO with a diagnostic accuracy of 86.2% using a cutoff value of 35 g [86]. Measurement of BWT or DWT and UEBW may be a feasible option for diagnosing BOO in men with LUTS.…”

“…[4] Obviously, for patients of any age, a reconstructive procedure is always indicated whenever overall renal function is compromised because of involvement in a solitary kidney or bilateral disease. [5] UPJO may not become apparent until middle age or later. [6] However, the majority of affected patients can in fact benefit from reconstructive intervention.…”

Stentless laparoscopic pyeloplasty: A single center experience

et al. 2014

Aim:To assess the effectiveness of laparoscopic stentless pyeloplasty for congenital ureteropelvic junction obstruction.Materials and Methods:This was a prospective comparative study conducted over a period of 5 years. The study included 35 cases of primary ureteropelvic junction obstruction (UPJO) with mean age of 29.5 years, divided in two groups- Group A (stent-less, 18 patients) and Group B (stented, 17 patients). Follow up ranged from one to 4years (mean 2 years). Transperitoneal laparoscopic Anderson- Hyene's pyeloplasty was standard for both the groups. Perioperative and postoperative complications were prospectively collected and analyzed by Statistical Package for Social Sciences (SPSS) 17 version using Pearson chi square test.Results:Both the groups were comparable with respect to preoperative differential renal function (DRF) and time required for maximum activity in minutes (tmax.min). Average post operative DRF was significantly higher than preoperative DRF in both the groups. Average tmax was significantly lower after pyeloplasty than pre operative tmax. Mean operative time, mean duration of urethral catheter, and mean duration of drain removal were comparable in both the groups. However bothersome irritative lower urinary tract symptoms (LUTS) and hematuria were significantly more in group B patients (P < 0.0001 and <0.013 respectively).Conclusion:In experienced hands, laparoscopic stentless pyeloplasty is as effective method for treating UPJO as its stented counterpart. It is cost effective, avoids stent-related morbidity, and could be performed without compromising the success rate. However, more randomized studies are needed to evaluate the safety of stentless pyeloplasty.
