Bladder outlet obstruction (BOO) produces compression or resistance upon the bladder outflow channel at any location from the bladder neck to urethral meatus. It may be induced by specific functional and anatomic causes. Functional obstruction may be caused by detrusor-sphincter dyssynergia (DSD) and anatomic obstruction most commonly from benign prostatic enlargement (BPH) or urethral stricture. Obstructive symptoms include hesitancy, sensation of incomplete bladder emptying, diminished urinary stream. The combination of PVR, urinary flow measures, and symptom appraisal has been generally accepted as the initial screening and evaluation paradigm for BOO. In, Ayurveda, BOO is similar to Mutraghata means obstruction in the urine flow. Uttarbasti is the prime treatment of Mutraghata. Present case is diagnosed as a functional bladder outlet obstruction (BOO) on the basis of symptoms, normal reports of USG and ascending urethrogram and diminished flow of urine in Uroflowmetry. Total 7 Uttarbasti with 50ml Sahcharadi Tailam was given along with Rasayana and Mutraghatahara medicine. Patient has complete relief in his obstructive urine complains and has normal urine flow without taking Tab. AFDURA after 7 years. And also improvement appear in Uroflowmetry.

Objective: The objective was to assess and publish our first experiences with the GreenLight XPS™ 180-watt laser in men suffering from bladder outlet obstruction. Patients and Methods: From January 2013 to February 2014, the results of 142 patients were analyzed prospectively at a single center. Indications for disobstruction were in line with current EAU guidelines, but independent of the underlying causes of obstruction. Assessments were made of the prostate size, International Prostate Symptom Score (IPSS), postvoid residual (PVR) and maximum urinary flow (Qmax). Intraoperative data such as lasing time, surgery time, applied energy and blood transfusions were recorded. Reinterventions and complications were evaluated. Results: The average prostate volume was 29.6 ml (2-82). The average surgery time was 50 min (13-157). Qmax increased by an average of 20.2 ml/s (p < 0.05). On average, PVR was reduced by 162 ml (p < 0.05). Conclusion: The GreenLight XPS™ 180-watt laser is an effective treatment option for bladder outlet obstruction with a low perioperative complications rate, and it shows results comparable with transurethral resection of the prostate. Even multimorbid patients and patients with long-term catheter requirements may be treated due to its high safety profile and reliable results.

Background: Notable number of prostatic carcinoma patients presented with bladder outlet obstruction. Among various treatment options like antiandrogen therapy, catheterisation, laser therapy, prostatic stent and pTURP, pTURP offers expeditious relief of symptoms. As, there is paucity of literature regarding outcome and complication of pTURP in Indian context. So, author did single centre indication (of surgery) matched retrospective case control study to know functional outcomes and morbidity of pTURP in eastern Indian population.Methods: Author did retrospective review of 29 patients who underwent pTURP during study period (January 2013 to January 2018) after exclusion. Same number of TURP (for benign disease) patients were selected. Functional outcome and complications of pTURP were compared with TURP group. Author also tried to find factors associated with un-favourable outcomes.Results: Despite of older pTURP group patients, operative duration, post-operative hospital stay, post-operative catheter duration and post-op maximum urinary flow rate, were statistically similar to TURP group. However, statistically similar but clinically more complication was noted in pTURP arm in terms of failed voiding trial, incontinence and re-operation rate. One capsular tear was noted only in TURP arm. Eight patients developed unfavourable outcome (1 persistent incontinence, 5 needed re-surgery and 2 required re-catheterisation in follow up period). Higher PSA, longer operative time and hormone refractory metastatic prostatic carcinoma were found to be associated with unfavourable outcome.Conclusions: pTURP is safe and effective procedure to relieve bladder outlet obstruction. Hormone refractory status, higher PSA and prolonged operative time may be risk factors of poor outcome.

The finding of bladder diverticula is often casual during investigations due to bladder outlet obstruction symptoms. The presence of infection, stones, tumours are usually the reference parameters for surgical treatment. From 1992 to 1997 we performed endoscopic diverticulectomy on 12 male patients aged between 20 and 76 years, with bladder acquired diverticula. We made the diverticulum neck incision with a Collins loop at the 4 cardinal points and then all the diverticulum surface was coagulated with a rollerball. In our experience endoscopic diverticulectomy has proved to be an effective technique with total disappearance of diverticula and residual urine.

Background: We compared the utility of the penile cuff test (PCT) and the conventional urodynamic study (UDS) for the preoperative assessment of patients undergoing scheduled photoselective vaporization of the prostate (PVP) for benign prostate hyperplasia (BPH). Methods: Fifty-nine patients with voiding lower urinary tract symptoms (LUTS) underwent a simultaneous PCT and conventional UDS before PVP. The modified International Continence Society (ICS) nomogram was used to confirm bladder outlet obstruction after measuring maximum urinary flow rate and highest pressure at flow interruption. The PCT and UDS results, in terms of modified ICS nomogram predictions, were compared. Their sensitivities, specificities, and positive and negative predictive values were calculated. Results: Thirty-six patients were diagnosed as obstructed and 23 as non-obstructed/equivocal using the modified ICS nomogram during the PCT. All 36 of the first group were confirmed as obstructed by UDS. Of the 23 diagnosed as non-obstructed/equivocal by the PCT, 14 were confirmed to be non-obstructed by UDS, with nine diagnosed as obstructed. The PCT showed a sensitivity of 80% and a specificity of 100%. The positive and negative predictive values were 100% and 60.9%, respectively. Conclusions: In conclusion, despite our small number of patients, the PCT’s high sensitivity and specificity suggest that it may provide diagnostic information about bladder outlet obstruction before PVP for patients with voiding LUTS. Evidently, the PCT has the potential to be used for some patients as a screening alternative to invasive UDS.
