Pelvic bone anatomy vs implanted gold seed marker registration for image-guided intensity modulated radiotherapy for prostate carcinoma: Comparative analysis of inter-fraction motion and toxicities.

OBJECTIVES: We compared the prostate motion variability and toxicities between patients treated with gold marker registration based IG-IMRT (IG-IMRT-M) and bony landmark registration based IG-IMRT (IG-IMRT-B). METHODS: T1c-T3b (node negative), intermediate and high risk (non-metastatic) adenocarcinoma of prostate, age ≥18years, Karnofsky Performance Status of ≥70 were included in this retrospective study. The prostate motion variability, acute and late radiation toxicities between the two treatment arms (IG-IMRT-M versus IG-IMRT-B) were compared. RESULTS: Total of 35 patients (17 for IG-IMRT-M and 18 for IG-IMRT-B) were treated with a median radiotherapy dose of 76 Gray. The prostate variability observed with and without markers in millimeter was 4.1±2.3 vs 3.7±2.1 [Antero-Posterior (A-P); p=0.001], 2.3±1.5 vs 2.1±1.2 [Superior-Inferior (S-I); p=0.095] and 1.1±1.7 vs 0.4±1.4 [Left-Right (L-R); p=0.003]. There was higher acute toxicity in IG-IMRT-B arm compared to IG-IMRT-M arm in terms of grade ≥2 diarrhea [50% vs 11% OR=7.5 (1.3-42.7); p=0.02] and grade ≥2 proctitis [38% vs 5.8%, OR=10.1 (1.09-94.1); p=0.04]. At a median follow up of 36months, the late genitourinary toxicities grade ≥2 [27% vs 0%; p=0.04] were higher in the IG-IMRT-B arm compared to IG-IMRT-M arm. CONCLUSIONS: IG-IMRT-M detects higher prostate motion variability as compared to IG-IMRT-B, inferring a significant prostate motion inside fixed pelvic bony cavity. The addition of marker based image guidance results in higher precision of prostate localization and lesser acute and late toxicities.

Are there any predictors of pyonephrosis in patients with renal calculus disease?

The objective of the study is to identify factors predicting development of pyonephrosis in patients of renal calculus disease (RCD), as this knowledge is largely unknown. Patients of RCD without pyonephrosis (Group 1) or with pyonephrosis (Group 2) presenting between December 2013 and November 2015 were evaluated. All patients of RCD who had undergone either percutaneous nephrostomy (PCN) or surgical management (percutaneous nephrolithotomy/pyelolithotomy/nephrectomy) were included. Patients treated conservatively, by extracorporeal shock-wave lithotripsy and patients of bilateral RCD were excluded. Data regarding demography, co-morbidities, associated urologic disease, previous intervention, clinical presentation, urinary culture, renal function, grade of hydronephrosis, stone characteristics were collected. 501 patients were included (Group 1: 410; Group 2: 91). Mean age in years (35.02 versus 35.48), sex ratio (2.12:1 versus 2.25:1) and mean body mass index (kg/m2) (22.27 versus 22.15) were similar in both groups. Prevalence of diabetes mellitus (3.41% versus 3.29%, p = 1.000) was similar. Group 2 patients had longer duration of symptoms (5.77 versus 8.96 months, p < 0.0001), associated urological diseases such as ipsilateral PUJO and ureteric calculus (4.63% versus 12.08%, p = 0.0125), moderate/severe-grade hydronephrosis (49.75% versus 92.30%, p < 0.0001), presence of staghorn calculus (20.73% versus 62.63%, p < 0.0001), multiple calculi (48.29% versus 68.13% p = 0.0007) and nonfunctioning kidney (1.70% versus 71.42%, p < 0.0001) as predictors of pyonephrosis. In logistic multivariate analysis, additionally, past history of urological surgery (p = 0.044) was found associated with pyonephrosis. Our study identified some conditions associated with patients of pyonephrosis. To prove their role as risk factors we recommend further studies.

Nocturia - Symptom or a Disease?

Waking at night to void is known as nocturia and it is a common condition experienced by both men and women with profound impact on patient's health, quality of life, and economic condition. It is often perceived as a symptom of an organic disease, but the pathophysiology of nocturia is now well-understood, and it is considered as a disease itself. It is classified based on four different pathophysiologic mechanisms (24-hour polyuria, nocturnal polyuria, reduced bladder capacity, and sleep disorders). The association of nocturia with impaired quality of life, cardiovascular morbidity and all-cause mortality is well established. Various pharmacological agents are available, of which desmopressin is considered safe and effective in both short- and long-term studies for the treatment of nocturia in men and women, including the elderly. Combining desmopressin with other agents provides an effective treatment option for nocturia in patients with lower urinary tract symptoms, benign prostatic hypertrophy or overactive bladder syndrome. This review covers the various aspects of pathophysiology and impact of nocturia, as well as the treatment of nocturia. We present the novel concept of a "nocturia clinic", which is a comprehensive diagnostic and management center for patients with nocturia. This set-up may help bring about a positive change in the underreported and undertreated status of nocturia, and bring relief to sufferers of nocturia. Therefore nocturia though perceived as a symptom of many disorders; it itself has a defined pathophysiology and needs treatment.

Meatal Occlusive Disease in Adult Males: Are There Any Clinical Variations?

OBJECTIVE: The study aimed to document the types of meatal occlusive disease (MOD) in adult males in terms of its clinical presentation, management and prognosis. MATERIAL AND METHODS: Eighty-six adult males with MOD were assessed during the study period. The patients were divided into Group 1, having meatal opening that was occluded by flimsy adhesions (meatal synechia/adhesive type MOD), and Group 2 that included patients who had circumferential constriction of the meatus (meatal stenosis/constrictive type MOD). All patients underwent meatal dilatation up to 18 Fr followed by self-dilatation for 3 months with topical clobetasol for 4 weeks. Degree of discomfort during self-dilation, improvement in flow rate, International Prostate Symptom Score (IPSS score) and recurrences were recorded at pre-determined intervals. RESULTS: Twenty-eight patients had meatal synechia (Group 1) and 48 had meatal stenosis (Group 2). Discomfort during self-dilatation in Group 1 patients was significantly less; there was improvement in IPSS and peak flow rate (mean follow-up 26.8 months) as compared to Group 2. With dilation alone, no recurrence was noted in Group 1; however, Group 2 showed 62.8% recurrence indicating poor outcome in this subset of patients. CONCLUSION: MOD in adult males consists of 2 separate clinical entities with different therapeutic outcomes.

Transurethral Bougie-guided Placement of Suprapubic Catheter Over Guide Wire Monorail in Females: A Novel Technique.

OBJECTIVE: To assess the safety and effectiveness of a novel transurethral bougie-guided monorail technique for suprapubic catheterization in females with vesicovaginal fistula. METHODS: Patients undergoing transvaginal vesicovaginal fistula repair from February 2013 to December 2013 were selected. Suprapubic catheter was placed using this technique and assessment was done in terms of time taken, intraprocedural dislodgement or entanglement of catheter during the procedure, bleeding from the anterior abdominal wall or urethra, or any other intraoperative difficulty. RESULTS: All patients were catheterized smoothly without any intraoperative difficulty, with a mean time of 6 minutes. CONCLUSION: We describe a new technique of performing suprapubic cystostomy in patients, especially where the bladder cannot be distended. It is safe and easy to perform.

Clinical utility of urinary soluble Fas in screening for bladder cancer.

AIM: Early diagnosis of carcinoma of urinary bladder remains a challenge. Urine cytology, as an adjunct to cystoscopy, is less sensitive for low-grade tumors. Soluble Fas (sFas), a cell-surface receptor and member of the tumor necrosis factor superfamily, is frequently expressed in urinary bladder carcinoma. The objective of this study was to investigate the urinary sFas for diagnosis of transitional cell carcinoma (TCC) of urinary bladder. METHODS: We examined urinary sFas concentration in 74 controls and 117 cases of TCC, both primary and recurrent disease, by using enzyme-linked immunosorbent assay and compared it with urinary cytology. RESULT: Urinary sFas concentration was found to be significantly higher in the patient as compared to control group (P < 0.05). An optimal cutoff value of 174.0 pg/mL was proposed. The urinary sFas level was found to have an approximate sensitivity and specificity of 88.03% and 89.19% (P < 0.001), whereas urine cytology had sensitivity of 66.67% and specificity of 95.95%. sFas had better sensitivity in higher grade and both primary and recurrent cases of urinary bladder cancer in comparison with cytology. Out of 15 node positive bladder cancer cases, 13 had high urinary sFas levels, whereas 12 were urinary cytology positive for malignancy. CONCLUSION: Urinary sFas can be used as a non-invasive diagnostic biomarker for TCC of urinary bladder, both for primary and recurrent disease.

SRD5A2 gene polymorphisms and the risk of benign prostatic hyperplasia but not prostate cancer.

BACKGROUND: Testosterone, a primary androgen in males, is converted into its most active form, dihydrotestosterone (DHT), by 5α-reductase type 2 (encoded by the SRD5A2 gene) in the prostate. DHT is necessary for prostatic growth and has five times higher binding affinity than testosterone for androgen receptors. We hypothesized that polymorphic variations in the SRD5A2 gene may affect the risk of benign prostatic hyperplasia and prostate cancer. MATERIALS AND METHODS: We analyzed SRD5A2 gene polymorphisms in 217 BPH patients, 192 PCa cases, and 171 controls. Genotyping was undertaken using direct DNA sequencing. Genotype data were compared between cases and controls using a Chi square statistical tool. RESULTS: We found that the A49T locus was monomorphic with 'AA' genotype in all subjects. At V89L locus, the presence of 'VV' showed a marginally significant correlation with increased BPH risk (p=0.047). At the (TA)n locus, longer TA repeats were found to be protective against BPH (p=0.003). However, neither of these polymoprhisms correlated with the risk of PCa. CONCLUSIONS: We conclude that A49T is monomorphic in the study population, VV marginally correlates with BPH risk, and longer (TA)n repeats are protective against BPH. None of these polymorphisms affect the risk of PCa.

Frequent expression of zinc-finger protein ZNF165 in human urinary bladder transitional cell carcinoma.

The aim of the study is to evaluate mRNA/protein expression of zinc finger protein 165 (ZNF165) in transitional cell carcinomas (TCCs) of urinary bladder and correlate its expression with the clinicopathological characteristics of patients. In this study, the methods of quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry (IHC) were utilized to evaluate mRNA/protein expression of ZNF165 in TCC. Independent Student's t test, ANOVA and Chi-square (χ(2)) were used to analyze the data statistically. We observed overexpression of ZNF165 mRNA in testis and majority (59.2%) of TCC patients. ZNF165 mRNA expression was also detected in adjacent noncancerous tissues (ANCTs) and some other normal tissues. Relative mean fold expression of ZNF165 mRNA was found to be significantly (p<0.01) higher in muscle-invasive bladder cancer (MIBC) as compared to non-muscle-invasive bladder cancer (NMIBC) patients. (12.11±9.57 vs. 5.72±2.61, p=0.009). ZNF165 protein expression was demonstrated on archival formalin-fixed, paraffin-embedded (FFPE) bladder tissues using IHC and nuclear staining pattern was detected. No significant difference was observed in protein expression of ZNF165 between the two groups (NMIBC and MIBC patients) (61.1% vs. 55.2%, p=0.629). No significant protein expression of ZNF165 was observed among ANCTs and benign prostatic hyperplasia (BPH) used as control. Our study results suggest that ZNF165 mRNA/protein expression was observed in TCC of human urinary bladder and might be used as a novel diagnostic biomarker and as well a vaccine target in development of urinary bladder cancer specific immunotherapy.

Significant association of metabolic indices, lipid profile, and androgen levels with prostate cancer.

OBJECTIVES: To compare the metabolic indices, lipid profile, androgens, and prostate specific antigen between prostate cancer and BPH and between grades of prostate cancer in a cross-sectional study. MATERIALS AND METHODS: The study enrolled 95 cases of prostate cancer and 95 cases of benign prostatic hyperplasia (BPH). Prostate gland volume was measured using transrectal ultrasound. We compared insulin, testosterone, dihydrotestosterone, prostate specific antigen levels and lipid profile between prostate cancer of different grades and BPH. Further, prostate cancer patients were classified into low grade and high grade. Unpaired t-test for normally distributed variables and Man-Whitney U test for non-normal variables were used to assess differences. RESULTS: We found that prostate cancer patients had significantly higher levels of insulin, testosterone, PSA, cholesterol, triglycerides, low-density lipoprotein (LDL) and very low-density lipoprotein (VLDL) in comparison to their BPH counterparts. Higher levels of these parameters also correlated with a higher grade of the disease. CONCLUSIONS: We conclude that higher levels of insulin, testosterone, PSA, and cholesterol correlate with a higher risk of prostate cancer, and also with a higher grade of the disease.

Testicular rerouting by modified Prentiss maneuver: usefulness in bilateral synchronous orchidopexy for high inguinal undescended testes.

OBJECTIVES: To describe our experience and illustrate the surgical procedure of synchronous bilateral testicular rerouting in high inguinal undescended testes (HIUT) by extending the use of "modified Prentiss maneuver" in bilateral situation, to establish this as a procedure of choice in bilateral HIUT and secondly to demonstrate the length gained by maneuver itself. METHODS: Between January 2011 and December 2012 ten boys (8months-6years) with diagnosis of bilateral HIUT were included in the study. Bilateral orchidopexy was done by "modified Prentiss maneuver" under general anesthesia. Postoperatively all patients were evaluated at 3 months ,6 months and 1 year by physical examinations and ultrasound. RESULTS: It was possible to reroute the testes underneath inferior epigastric artery (IEA) without its mobilization and thus locate testicular pedicle through a fascial hole above pubic tubercle, well medial to IEA. The average gain in scrotal positioning was 16mm (10-22mm).No retractions, atrophy of testis, clinical weakness of anterior abdominal wall or inguinal herniation was noted in any patient up to one year follow up. CONCLUSIONS: Testicular re-routing by "modified Prentiss maneuver" is a simple, feasible, safe and efficient method for bilateral orchidopexy in bilateral HIUT. Preserving the inferior epigastric artery bilaterally has physiologic advantages.

Prevention of prostate cancer with vitamins - current perspectives.

Cancer prostate is the most common solid malignancy in males of developed countries. With increasing knowledge of the aetiology, pathogenesis and natural history of the disease, influences of dietary factors on prostate cancer development have become more evident. There is ample evidence in the literature of significance of dietary constituents for prostate cancer including vitamins A, D and E. Different vitamins have been found to effect the growth and proliferation of prostate cancer cells as evident in epidemiological, experimental and clinical studies. Various factors play the major role in determining the relationship between these vitamins and prostate cancer in terms of environmental, pharmacological, or genetic aspects. To explore these aspects, the present article reviews the literature on the present status of vitamin use for prevention and management of prostate cancer.

Single dose silodosin prior to voiding cystourethrogram: a pharmacological adjunct to enhance visualization of posterior urethra.

Voiding cystourethrogram (VCUG) is needed to ascertain the upper end of urethral stricture. Occasionally, a patient is unable to open the bladder neck with resultant failure of the test. Realizing the strong and prompt alpha antagonistic action of silodosin, we evaluated single 8 mg dose as a pharmacological adjunct prior to VCUG to overcome this problem.

Factors affecting response to medical management in patients of filarial chyluria: A prospective study.

INTRODUCTION: Filarial chyluria is a common problem in filarial endemic countries. Its management begins with medical therapy but some patients progress to require surgery. The present study aimed to determine factors affecting response to medical management in patients of filarial chyluria. MATERIALS AND METHODS: This prospective study conducted between August 2008 and November 2012, included conservatively managed patients of chyluria. Demographic profile, clinical presentation, treatment history and urinary triglycerides (TGs) and cholesterol levels at baseline were compared between the responders and non-responders. Apart from the clinical grade of chyluria, hematuria was evaluated as an independent risk factor. RESULTS: Out of the 222 patients (mean age, 37.99 ± 13.29 years, 129 males), 31 patients failed to respond while 35 had a recurrence after initial response; the overall success rate being 70.3% at a mean follow-up of 25 months. No difference was observed in demographics, clinical presentation, presence of hematuria, disease duration and mean urinary TGs loss between responders and non-responders. On multivariate analysis, patients with treatment failure were found to have a higher-grade disease (14.3% Grade-I, 36.6% Grades-II and 60% Grade-III), higher number of pretreatment courses (1.59 ± 1.08 vs. 1.02 ± 0.79) and heavier cholesterol (26.54 ± 23.46 vs. 8.81 ± 8.55 mg/dl) loss at baseline compared with responders (P < 0.05). CONCLUSION: Conservative management has a success rate in excess of 70%, not affected by the disease chronicity, previous episodes and recurrent nature. However, higher-grade disease, extensive pre-treatment with drugs and higher urinary cholesterol loss at baseline are the predictors of poor response. Hematuria is not an independent poor risk factor for conservative management.

Short-term morbidity following No-Scalpel Vasectomy: an assessment of clients' perceptions by novel postcard system.

OBJECTIVE: Data on short-term (within a week) morbidity of No-Scalpel Vasectomy (NSV) is lacking. We studied clients' perceptions of early post-vasectomy morbidity by self innovated postcard pictorial questionnaire. METHODS: Between March 2011 and April 2012, 821 men underwent NSV and provided pre-printed revalidated pictorial postcards depicting various grades of severity of local pain, swelling, and bleeding. Clients were asked to tick mark their problems and post them on the third day after NSV. Data were compiled and statistically analyzed. RESULTS: Completed postcards were returned by 702 clients (85.5%). 25 postcards were excluded due to illegitimate filling of card. About 80.8% of clients complained of pain and minimal, moderate and severe pain was experienced by 77.69%, 18.09% and 4.20%, respectively. 16.24% of clients observed local swelling, which was minimal in 90.9%, moderate and severe in 7.27% and 1.81% of cases. 2.95% of clients noted mild bloody discharge. Most of clients managed their problems by following the instructions given in postcards; level 1 and 2 morbidity did not affect their daily activity. CONCLUSION: Early morbidity after NSV is usually mild in severity and easily manageable. The postcard system is a feasible, effective, and economical way of collecting data and managing short-term post NSV problems.

Effect of intravesical immunotherapy on sperm parameters in young patients with non--muscle-invasive bladder carcinoma: prospective analysis.

INTRODUCTION: To investigate the effects of intravesical immunotherapy on semen parameters in young patients with non-muscle invasive bladder tumour. METHODS: A total of 17 sexually active male patients < 45 years of age underwent transurethral resection of bladder tumour (TURBT) from Jan 2010 to Dec 2012. On HPE analysis, T1 high grade was found in 16 patients and Ta grade high grade in 1 patient. Associated CIS was found in 4 patients. Induction course of 6 weeks of adjuvant BCG therapy was given. Semen analysis was done 1 week prior to BCG therapy and 3 months after BCG therapy. Serum levels of hormones like total testosterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were also measured. RESULTS: Mean age of patients at diagnosis was 34.6 (29-43) years. Total semen volume was found to be decreased in 2 patients. Main parameter which was deteriorated was total sperm concentration which was significantly decreased in 12 patients and 5 patients even had their counts below oligospermia levels. Seven patients had associated decrease in sperm motility. However, no patient showed significant difference in other semen parameters. Also no patient had any change in androgen hormonal status except 2 patients in which serum testosterone was found to be non-significantly decreased. CONCLUSION: Intravesical therapy with BCG was found to adversely affect spermatogenesis and cause oligospermia. It is important that relatively young patients must be informed of these effects and advised to have sperm preservation before instillation of BCG therapy to avoid fertility issues in future.

Effect of phallic stretch on length of bulbous urethral stricture during retrograde urethrography.

OBJECTIVE: The purpose of this study was to evaluate the effect of phallic stretch on bulbous urethral stricture while performing retrograde urethrography (RUG). METHODS: Between July 2009 and June 2012, 197 adult males with stricture pattern on uroflowmetry underwent RUG. Two films were taken, first without (film A) and second after stretching the penis by about 5 cm (film B). 29 cases with proximal and distal bulbous strictures were included in the present analysis. The data recorded were stricture lengths in films A and B. RESULTS: 12 men had distal bulbous or penobulbous stricture (group 1) while 17 had stricture involving the proximal bulb (group 2). Mean stricture length in group 1 was 2.82 cm (range 1.2-4.2 cm) in film A and 4.59 cm (range 3.0-6.4 cm) in film B. In group 2 stricture length was 1.76 cm (range 1.0-2.3 cm) in film A and 1.79 cm (range 1.0-2.5 cm) in film B. The percentage change in stricture length on stretching was 38.48% (p = 0.0001) in group 1 and 1.67% (p = 0.8301) in group 2. CONCLUSIONS: The impact of phallic stretch on radiographic length during RUG was found to be significant in distal bulbous but not in proximal urethral stricture, which is important when interpreting the RUG and deciding the management of stricture.

Dorsal onlay buccal mucosal graft urethroplasty in female urethral stricture disease: a single-center experience.

INTRODUCTION AND HYPOTHESIS: The aim of this report is to present our initial, short-term experience with dorsal onlay buccal mucosal graft urethroplasty (DBMGU) in women with urethral stricture. METHODS: Between May 2011 and April 2013, eight women with moderate to severe bothersome lower urinary tract symptoms due to mid- or distal urethral stricture underwent DBMGU. All women were evaluated preoperatively with the American Urological Association (AUA) symptom score, uroflowmetry with post-void residual volume (PVR) estimation, urodynamic study, calibration with 14 F catheter, and voiding cystourethrography. Postoperatively, the women were followed at regular intervals with AUA symptom score, uroflowmetry, and PVR estimation. Increase in AUA symptom score, maximum flow rate (Q(max)) < 12 ml/s, and failure to calibrate with 18 F catheter were considered as recurrence of the disease. RESULTS: The mean age of the patients was 40.6 years. The mean follow-up period was 14.8 months. All women voided successfully after catheter removal. One patient was lost to follow-up after 3 months. There was significant improvement in AUA symptom score and Q(max) and reduction in PVR (p < 0.0001) at 3, 6, and 9 months. Two women had recurrence of stricture at 12 months, while another had recurrence at 18 months which was treated by urethral dilatation followed by a self-dilatation protocol. The limitations of the study include the small number of cases with short follow-up. CONCLUSIONS: DBMGU is a simple and safe method of urethroplasty in women with unsatisfactory results. Large size studies with long-term follow-up are desirable to document the success rates.

A critical appraisal of complications of percutaneous nephrolithotomy in paediatric patients using adult instruments.

OBJECTIVE: To evaluate the complications (using the CROES Clavien scoring system) and various factors affecting them in children undergoing percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS: We analysed prospectively maintained data of paediatric PCNL (patients ≤17 years) from January 2008 to December 2012. Stone complexity was defined according to validated Guy's stone score (GSS). Procedures were performed in the prone position by experienced urologists. The tract was dilated (24-30F) under fluoroscopic guidance, and an adult rigid nephroscope complemented with a cystoscope/ureteroscope were used. Complications were recorded according to the CROES-Clavien score, recently defined by the Clinical Research Office of the Endourological Society (CROES) Study Group. RESULTS: The study group comprised 158 procedures performed in 153 children (98 boys and 55 girls), with a mean (range) age 10.03 ± 4.51 (2-17) years. The mean (range) stone burden was 376.68 ± 265.23 (150-2400) mm(2) . The distribution of cases according to the GSS was 31% grade I, 35.4% grade II, 19% grade III, and 14.6% grade IV. The stone-free rate of PCNL monotherapy was 85.4%, which increased to 93.7% after relook PCNL/extracorporeal shock wave lithotripsy. In all, 62 children (39.2%) had operative complications; 84% were minor, i.e. Clavien grade 1/2, and managed conservatively. Stone size, GSS, tract size, number of punctures and operation duration were significantly associated with complications on univariate analysis (P < 0.05). However, on multivariate logistic regression analysis, operation duration was the only independent risk factor associated with complications (95% confidence interval: 1.013-1.065, odds ratio = 1.04; P = 0.038). CONCLUSIONS: Percutaneous nephrolithotomy in children using adult instruments is an effective and safe procedure for managing simple as well as complex renal calculi. Assignment of specific Clavien scores to all possible PCNL complications by the CROES PCNL Study Group have improved precision in reporting complications in a standard objective format, including the minor ones. Such models are very useful for making inter-observer comparisons to obtain clinically relevant inferences. Mean operation duration is the only independent factor affecting complications of the procedure.

Transurethral resection of prostate abscess: is it different from conventional transurethral resection for benign prostatic hyperplasia?

Purpose. To present our experience of prostate abscess management by modified transurethral resection (TUR) technique. Methods. Seventeen men with prostate abscess undergoing TUR between 2003 and 2011 were retrospectively analyzed. Details of demography, surgical procedures, complications, and followup were noted. Results. With a mean age of 61.53 ± 8.58 years, all patients had multifocal abscess cavities. Initially, 6 men underwent classical TUR similar to the technique used for benign prostatic enlargement (group 1). Next, 11 men underwent modified TUR (group 2) in which bladder neck and anterior zone were not resected. The abscess cavities resolved completely, and no patient required a second intervention. One patient in group 1 and three in group 2 had postoperative fever requiring parenteral antibiotics (P = 0.916). Three patients in group 1 had transient urinary incontinence, whereas none of the patients in group 2 had this complication (P = 0.055). Four and five men in group 1 and 2 reported retrograde ejaculation, respectively (P = 0.740). Conclusion. The modified technique of prostate resection edges over conventional TURP in the form of reduced morbidity but maintains its high success rate for complete abscess drainage. It alleviates the need for secondary procedures, having an apparent advantage over limited drainage techniques. Use of this technique is emphasized in cases associated with BPH and lack of proper preoperative imaging.

Congenital anterior urethral valve with or without diverticulum: a single-centre experience.

INTRODUCTION: Congenital anterior urethral valves (AUV) are rare and can occur as an isolated entity or in association with proximal diverticula. Diagnosis may be overlooked and ideal treatment is not standardized when both the valve and diverticulum are simultaneously present. We present our experience of congenital AUV. MATERIAL & METHODS: From January 2007 to June 2012 a retrospective review of the medical records of 7 cases of AUV was performed. RESULTS: Three patients were diagnosed as isolated AUV while four presented with associated diverticula. The age of presentation ranged from 10 months to 6 years. Weak voiding stream and dribbling were the most common symptoms. Renal function was found to be deranged in two patients (28%). Hydro-ureteronephrosis was present in three boys (42%) and reflux was present in one patient. Post-void residual volume was >20 ml (mean 55 ml) in all children. Transurethral holmium laser fulguration was carried out on isolated AUV or AUV with small diverticula. Open resection and reconstruction or plication was performed in patients with AUV and proximal large (>3 cm) diverticula. Surgical outcome was successful in all patients except for occurrence of urethrocutaneous fistula in one patient. CONCLUSIONS: In isolated AUV or valve with associated small diverticulum, transurethral holmium:YAG laser ablation is the treatment of choice. Primary excision and repair or plication are preferred if a large diverticula has formed. Eventual outcomes of AUV are good if irreversible changes have not been established.
