The infodemics of COVID-19 amongst healthcare professionals in India.

BACKGROUND: There is a deluge of information and misinformation about COVID-19. The present survey was conducted to explore the sources of information /misinformation for healthcare professionals from India. METHODS: A cross-sectional online survey using snowballing technique was conducted from 24 Mar to 10 Apr 2020. The questionnaire was pretested and developed using standard techniques. It was circulated among medical students and physicians. Data were analysed using the STATA software. RESULTS: Data of 758 participants were analysed. A total of 255 (33.6%) medical students, 335 (44.2%) nonspecialists and 168 (22.1%) specialists participated. The most common source of formal and informal information was official government websites and online news, respectively. A total of 517 (68.2%) participants accepted receiving misinformation. Social media and family and friends were the most common sources of misinformation. Seventy-two percent of participants agreed that spread of information helped to contain COVID-19, but more than that 75% agreed to having received inaccurate information. Seventy-four percent of respondents felt the need for regulation of information during such times; 26% and 33% felt that information about COVID-19 made them feel uncomfortable and distracts routine decision-making, respectively, and 50% felt it was difficult to differentiate correct from incorrect information about COVID-19. CONCLUSION: The study explored the sources of information and misinformation and found a high prevalence of misinformation, especially from social media. We suggest the need to better manage the flow of information so that it can be an effective weapon against SARS-CoV2. There is a need for doctors to adapt to the changing times of infodemics accompanying pandemics.

Prospective randomized comparison of repairing vesicovaginal fistula with or without the interposition flap: Result from a tertiary care Institute in Northern India.

OBJECTIVE: Assessment of results of repairing vesicovaginal fistula (VVF) with or without the use of interposition flaps. MATERIAL AND METHODS: This prospective randomized study was conducted between January 2012 to December 2017 in the Department of Urology, King George's Medical University, Lucknow, India. Obstetric and gynecological simple fistula of ≤4 cm were included for evaluation. Those with complex or complicated fistula or fistula due to malignancy were excluded. Patients were divided into two groups (group 1 and group 2) depending upon route of repair i.e., transvaginal or transabdominal, respectively, as per the characteristics and location of the fistula. These two groups of patients were randomized into two subgroups (1A, 1B and 2A, 2B) based on the inclusion or omission of the interposition flap during fistula repair. Perioperative and postoperative parameters (blood loss, mean operating time, hospital stay, and requirement of analgesics) and success rates of fistula repair were compared. All complications that occurred in the postoperative period till the last follow-up appointment were recorded. The Clavien-Dindo Classification was used to stratify the complications. RESULTS: Fifty-seven patients underwent transvaginal repair in group 1 (29 with Martius flap: group 1A; 28 without Martius flap: group 1B), while 69 patients underwent transabdominal repair in group 2 (35 with interposition flap: group 2A; 34 without flap: group 2B). Blood loss, mean operating time, hospital stay, and the requirement of analgesics were comparable between each subgroup-1A versus 1B and 2A versus 2B, respectively. The overall success rate of repair across all groups was 96.04% (121/126). The success rate was 93.1% in transvaginal repair with Martius flap versus 96.43% in transvaginal repair with no flap (p=1.0). Success rate was 97.1% in transabdominal repair with an omental flap versus 97.06% in without an omental flap (p=1.0). Mean follow-up period was 39.6 months (range: 6-68 months). Out of 29 patients with Martius flap interposition, 9 (31.03%) of them reported a significantly reduced sensation on the labia majora. Of these 9 patients, 5 reported numbness while the remaining 4 experienced pain as compared to the patients in subgroup IB, who did not report any altered sensation in the labia. (p=0.0019). CONCLUSION: The success rates are similar in simple VVF repair (fistula size less than 4 cm) irrespective of the use of interposition flaps. However, overall morbidities following repair with the interposition flap are higher when compared with repair without interposition flap, either by the transvaginal or by the transabdominal route.

A retrospective analysis of complications of laparoscopic left donor nephrectomy using the Kocak's modification of Clavien-Dindo system.

INTRODUCTION: Kocak described a modification of Clavien-Dindo classification system (CDCS) for reporting procedure-related complications in laparoscopic donor nephrectomy (LDN). We used the Kocak modification in grading and reporting the severity of complications in patients who underwent LDN and in evaluating various parameters that predict them. METHODS: In all, 1430 patients who underwent left LDN from 2000 to 2016 were included in this study. All data was retrospectively collected and analyzed for complications occurring in the postoperative period. All complications were classified according to the four grades of Kocak-modified CDCS. RESULTS: 124 patients (8.6%) suffered a total of 235 postoperative complications. Most of the complications were Grade I and Grade II (Grade I: 79.5% [n = 187] and Grade II 16.2% [n = 38]), 2.5% of the complications were Grade III (n = 6) and Kocak Grade IVa complications occurred in three patients. There was one death (Grade IVb: 0.4%, overall mortality rate: 0.06%). The incidence of complications was significantly greater for male patients, those with body mass index ≥25 kg/m2, and if the operating surgeon had ≤ 1 year of experience in performing LDN surgery. CONCLUSION: LDN is a safe procedure with low morbidity. The rate of complications is 8.6% and most of these complications are of low grade. The use of a standardized system for reporting the complications of LDN allows appropriate comparison between reported data.

Bladder contractility index in posterior urethral valve: A new marker for early prediction of progression to renal failure.

INTRODUCTION: Posterior urethral valve (PUV) is the most common cause of pediatric end stage renal disease (ESRD), imposing a major health burden on medical community caregivers and adversely affecting the quality of life of patients. Chronic kidney disease (CKD) stage III or estimated GFR of <60 mL/min/1.73 m2 is known to be associated with more adverse renal, cardiovascular, and clinical outcomes. Thus, it is desirable to identify factors predicting the rapid and early progression of disease. In the present study, baseline characteristics and urodynamic study (UDS) parameters of boys with PUV are correlated with CKD progression to IIIB or more. AIMS AND OBJECTIVES: To study the correlation of bladder contractility index (BCI) with development of CKD stage IIIB (eGFR of <45 mL/min/1.73 m2) or more in boys with PUV. METHODOLOGY: Baseline characteristics and demographical variables of 270 boys with PUV who underwent valve fulguration at the hospital between 2000 and 2010 were recorded and certain UDS parameters in follow-up were noted such as bladder contractility index (BCI = PdetQmax + 5 Qmax), end filling pressure (EFP), compliance (ΔC), bladder outlet obstruction index (BOOI = Pdet Qmax - 2 Qmax), and bladder volume efficiency (BVE = Voided volume/total capacity). Fate of patients in follow-up was checked in December 2015. RESULTS: Mean follow-up period was 8.5 years (range 5-15) and median age of patients at the time of evaluation was 5.8 years. At the end of the study, 21.8% (59/270) of patients had progressed to CKD stage IIIB or more (primary end point). Cox regression analysis was applied to risk factors predicting development of CKD stage IIIB. In the multivariate model, bladder contractility index (BCI) (HR 0.8; p = 0.004), end filling pressure (EFP) (HR 2.1; p = 0.010), and compliance (ΔC) (p = 0.020) were significantly associated with the event (i.e. an eGFR of <45 mL/min/1.73 m2), whereas BOOI (p = 0.053) and bladder BVE (p = 0.267) were not. ROC cut-off level for BCI predicting the primary end point was 75 (AUC ± SE, 0.73 ± 0.03, sensitivity of 78.2%, and specificity of 62.5%). CONCLUSION: In a well performed UDS, BCI may be a useful tool for early detection of boys with PUV who are likely to progress to CKD stage IIIB or more.

Can baseline serum creatinine and e-GFR predict renal function outcome after augmentation cystoplasty in children?

ABSTRACT Objective To assess cut-off value of creatinine and glomerular filtration rate for augmentation cystoplasty (AC) in paediatric age-group. Materials and Methods Data of all paediatric-patients (<18 years) with small capacity bladder, in whom AC was advised between 2005-2015 were reviewed. All patients were divided in two-groups, AC-group and control-group (without AC). Creatinine and e-GFR were assessed at the time of surgery, at 6 months and at last follow-up. Renal function deterioration was defined as increase in creatinine by ≥25% from baseline value or new-onset stage-3 CKD or worsening of CKD stage with pre-operative-CKD stage-3. ROCs were plotted using creatinine and e-GFR for AC. Results A total of 94 patients with mean-age 8.9 years were included. The mean creatinine and e-GFR were 1.33mg/dL and 57.68mL/min respectively. Out of 94 patients, AC was performed in 45 patients and in the remaining 49 patients AC was not done (control-group), as they were not willing for the same. Baseline patient's characteristics were comparable in both Groups. 22 underwent gastro-cystoplasty (GC) and 25 underwent ileo-cystoplasty (IC). Decline in renal function was observed in 15 (33.3%) patients of AC-group and in 31 (63.3%) patients of control-group. Patients having creatinine ≥1.54mg/dL (P=0.004, sensitivity (S) 63.6% and specificity (s) 90.5%) at baseline and e-GFR ≤46mL/min (P=0.000, S=100% and s=85.7%) at the time of surgery had significantly increased probability of renal function deterioration on follow-up after AC. Conclusion e-GFR ≤46mL/min and creatinine ≥1.54mg/dL at time of surgery could serve as a predictor of renal function deterioration in AC in paediatric patients.

CONCLUSION: e-GFR ≤46mL/min and creatinine ≥1.54mg/dL at time of surgery could serve as a predictor of renal function deterioration in AC in paediatric patients.

What is the fate of insignificant residual fragment following percutaneous nephrolithotomy in pediatric patients with anomalous kidney? A comparison with normal kidney.

Pediatric population has increasing incidence of renal calculus and it is estimated to be around 50/10,000 population. The treatment of choice for large and complex stone in anomalous kidney is percutaneous nephrolithotomy (PCNL). The fate of insignificant residual fragment after PCNL in pediatric patients is not well documented. Here, we are reporting our long-term experience and follow-up of insignificant residual fragment in pediatric patients with anomalous kidney in comparison to normal kidney. Intuitional ethical approval was taken. A retrospective analysis of PCNL in pediatric (<18 years) anomalous kidney was performed from 2001 to 2013. The data of 52 pediatric patients with anomalous kidney (group B) have been compared to 251 normal kidneys (group A). The mean age of the patients was 7.83 + 3.45 (range 3-18) in group A and 8.21 ± 3.25 (range 5-18) in group B. The mean size of the insignificant residual fragment was 2.2 + 0.5 mm (1-4) in group A and 2.1 + 0.6 mm (range 1-4) in group B. Most of these residual fragments were single in number (72.55 vs. 67.30%, respectively). 54.98% children in group A and 67.30% in group B were symptomatic in the follow-up. Stone size was increased, stable and spontaneously passed in 49.8 vs. 71.15, 22.7 vs. 19.23 and 27.49 vs. 9.61% (p < 0.03), respectively, over mean follow-up of 50.34 months. Insignificant residual fragments in children are notorious for regrowth (49.8% in normal and 71.15% in anomalous kidney) in future. Most of the children will require symptomatic treatment (55.37 vs. 82.69%) or reintervention (39 vs. 46%) for insignificant residual fragment.

Outcome analysis of transrectal ultrasonography guided aspiration versus transurethral resection of prostatic abscess: 10 years' experience from a tertiary care hospital.

OBJECTIVE: To compare the effectiveness and safety of two minimally invasive methods (transrectal aspiration vs transurethral resection (TUR)/deroofing) of treating prostatic abscess. PATIENTS AND METHODS: A retrospective study was conducted, from 2007 to 2016, of patients with prostatic abscesses not responding to antibiotics and/or with large (>2 cm) or multiple abscesses. Patients were divided into two groups depending on treatment received: Group A, transrectal aspiration; and Group B, TUR/deroofing of abscess. RESULTS: The most common clinical presentation was dysuria (81.8%), followed by urinary frequency (68.2%), and fever (36.4%). Acute urinary retention occurred in seven patients. The most common infective organism in both groups was Escherichia coli (43.9%). The mean (SD, range) prostate volume was 36 (6.4, 17-68) mL and 37 (7.3, 21-72) mL in Groups A and B, respectively. The mean (SD, range) volume of the abscess was 51.24 (12.6, 21-215) mL and 48.34 (15.4, 15-240) mL in Groups A and B, respectively. Overall, 37 (84.1%) patients responded to treatment (68.4% in Group A and 96.0% in Group B, P < 0.23) after the first treatment session. Six patients in Group A and one patient in Group B had recurrence of abscess (P < 0.03). Of the six patients in Group A with recurrence, four patients had complete resolution after repeat aspiration (average 1-3 times). The mean (SD) follow-up duration was 17.25 (6.3) months. CONCLUSION: TUR of prostatic abscess is more effective (96%) than transrectal aspiration with a lesser hospital stay. However, transrectal aspiration was successful in 89% of cases, is less invasive and can be performed under local anaesthesia and or sedation.

Laparoscopic ureteral reimplantation with Boari flap for the management of long- segment ureteral defect: A case series with review of the literature.

OBJECTIVE: The incidence of ureteral stricture is showing a rising trend due to increased use of laparoscopic and upper urinary tract endoscopic procedures. Boari flap is the preferred method of repairing long- segment ureteral defects of 8-12 cm. The procedure has undergone change from classical open (transperitoneal and retroperitoneal) method to laparoscopic surgery and recently robotic surgery. Laparoscopic approach is cosmetically appealing, less morbid and with shorter hospital stay. In this case series, we report our experience of performing laparoscopic ureteral reimplantation with Boari flap in 3 patients. MATERIAL AND METHODS: This prospective study was conducted between January 2011 December 2014. The patients with a long- segment ureteral defect who had undergone laparoscopic Boari flap reconstruction were included in the study. Outcome of laparoscopic ureteral reimplantation with Boari flap for the manangement of long segment ureteral defect was evaluated. RESULTS: The procedure was performed on 3 patients, and male to female ratio was 1:2. One patient had bilateral and other two patient had left ureteral stricture. The mean length of ureteral stricture was 8.6 cm (range 8.2-9.2 cm). The mean operative time was 206 min (190 to 220 min). The average estimated blood loss was 100 mL (range 90-110 mL) and mean hospital stay was 6 days (range 5 to 7 days). The mean follow up was 19 months (range 17-22 months). None of the patients experienced any complication related to the procedure in perioperative period. CONCLUSION: Laparoscopic ureteral reimplantation with Boari flap is safe, feasible and has excellent long term results. However, the procedure is technically challenging, requires extensive experience of intracorporeal suturing.

Outcome analysis of transurethral resection versus potassium titanyl phosphate-photo selective vaporization of the prostate for the treatment of benign prostatic hyperplasia; a randomized controlled trial with 4 years follow up.

OBJECTIVE: Photovaporization of prostate (PVP) is a newer surgical modality of benign prostatic hyperplasia (BPH) which is gaining importance recently. There are a few randomized controlled trials that showed safety and efficacy of PVP in comparison with transurethral resection of prostate (TURP) with limited follow-up period (<2 years). Here, we are presenting a comparative study performed on potassium titanyl phosphate (KTP) PVP laser versus TURP for the treatment of BPH with long-term follow-up period. MATERIAL AND METHODS: After institutional ethical clearance, 150 patients were prospectively included in the study from January 2010 to March, 2012. Improvement of International Prostate Symptoms Score (IPSS), Qmax, post-void residual (PVR) urine, International Index of Erectile Function (IIEF)-5 score and complications were assessed at 12, 24, 36 and 48 months. RESULTS: Mean age of the study group was 65.3±7.86 years in the TURP and 63.6±8.12 years in the PVP groups (p=0.45). IPSS symptom score improved significantly in both TURP and KTP groups (p<0.003). There was improvement in Q max during follow-up in both groups (p<0.001) which was maintained at 48 months. Most of the patients in both groups were satisfied with symptoms and bothersome at 48 months. All the sexual parameters are similar to both groups except retrograde ejaculation. Overall complication noted in 23 patients (15.33%). CONCLUSION: Both KTP Laser PVP and TURP afford durable relief from symptoms of BPH at 48 months follow-up. Both procedures are safe and associated with minimal complications. Both procedures do not have any detrimental effect on sexual function on long-term follow-up. Quality of life remains high even at 4 years in both groups.

Emphysematous pyelonephritis: Changing trend of clinical spectrum, pathogenesis, management and outcome.

OBJECTIVE: To highlight changing trend of clinical spectrum, comparing management options and predictors of outcome of emphysematous pyelonephritis. MATERIAL AND METHODS: This study included patients who were diagnosed as emphysematous pyelonephritis between August, 2001 to July, 2015. We excluded other possible causes of gas in renal system. Baseline patient characteristics, clinical spectrum, serum and urinary biochemical parameters, radiological findings, management and outcomes were recorded. Patients were classified as "responders" and "non-responders". RESULTS: We studied a total of 74 patients and categorised them as responders (62 patients) and non-responders (12 patients). Women outnumbered men constituting 62.16% of the study population (M: F; 1: 1.6). Fever was the most common presenting symptom followed by flank pain. Diabetes mellitus (85.14%) was the most common comorbidity followed by urolithiasis (32.43%). Escherichia coli was the commonest organism grown in urine culture (79.73%). Non-responders had distinct laboratory findings relative to responders as low hemoglobin (7.8±2.1/11.2±3.2 g/dL; p=0.0007), thrombocytopenia (91.67% vs. 11.29%; p=0.0001), proteinuria >3 g/L (50% vs. 6.45%; p=0.0008) and positive blood culture (100% vs. 67.74%; p=0.0288). CONCLUSION: Advanced age, higher body mass index, renal impairment, thrombocytopenia, altered sensorium, shock at presentation can be used as scores for poor prognosis. Emphysematous pyelonephritis management requires multidisciplinary collaboration including hydration and electrolyte management, broad spectrum antibiotics, strict glycaemic control, effective urinary drainage and lastly it may require emergency nephrectomy as a salvage procedure.

Multidimensional assessment of quality of life of children and problems of parents in Indian society after pediatric renal transplant: Beyond the conventional thoughts.

This study evaluated multidimensional QoL after renal transplant to find the physical, psychosocial, and economic issues after pediatric transplant. Sixty-two patients under the age of 18 at the time of assessment were asked to complete WHOQOL questionnaires. Assessment of behavioral, emotional status of child, problems of parents, and SEC of family were also performed. The beneficial effect of transplantation was observed across all domains of QoL (physical, psychological, social, environmental, and overall QoL). The greatest change was observed in QoL domains that dealt with overall satisfaction (81.28±15.76 vs 45.32±10.98; P<.0001). The domain dealing with environmental factors showed the least variation after transplantation (65.58±17.45 vs 51.34±17.81; P<.0001). Feelings of happiness and peer group socialization were reported in 81% and 69% of patients, respectively. There was no marital disharmony in 52% of families. However, SEC deteriorated in 16% of families and 59% of the families availed financial assistance. Sixty-nine percent of children had not attended school after one year of transplantation, but return to school after transplant was reduced to 8% at 5 years. Pre- and post-transplant social and psychological support may help these patients and their families adjust in society and have a positive outlook for their future.

Transurethral Resection of Prostate and Bleeding: A Prospective, Randomized, Double-Blind Placebo-Controlled Trial to See the Efficacy of Short-Term Use of Finasteride and Dutasteride on Operative Blood Loss and Prostatic Microvessel Density.

OBJECTIVE: The aim of this study was to determine the efficacy of short-duration use of finasteride and dutasteride before transurethral resection of the prostate (TURP) on intraoperative blood loss and microvessel density (MVD) of prostate stroma and suburethral tissues in benign prostatic hyperplasia (BPH). METHODS: This study includes 450 patients who were planned for TURP. They were prospectively randomized into three groups (150 patients each). Group 1 received placebo, group 2 received finasteride, 5 mg per day, and group 3 patients received dutasteride, 0.5 mg per day, for 4 weeks before surgery. The total blood loss, requirement of blood, and MVDs in prostate stroma and suburethral tissues were calculated in each patient and then compared among three groups. RESULTS: There was significant reduction in mean blood loss, blood loss/time, and total blood loss per gram of resected tissue in finasteride and dutasteride groups compared with placebo. Prostate stromal and suburethral MVDs were significantly higher compared with placebo. Blood transfusion was required in 9.3%, 2.7%, and 2% of the patients, respectively (p = 0.004). However, no statistically significant differences were observed between finasteride and dutasteride groups for these parameters (p > 0.05). The weight of resected prostate, operating time, and amount of irrigation fluid used did not show any significant difference between the three groups. CONCLUSION: Short-term pretreatment with finasteride and dutasteride has similar efficacy and significantly reduces perioperative bleeding during TURP and has minimal negative impact on sexual function. According to our findings, a 4-week prior administration of 5-alpha-reductase inhibitors may reduce operative blood loss and prostatic MVD in TURP, thus potentially decreasing blood loss-related complications and the requirement of blood transfusion.

Ureterocalicostomy for Reconstruction of Complicated Ureteropelvic Junction Obstruction in Adults: Long-Term Outcome and Factors Predicting Failure in a Contemporary Cohort.

PURPOSE: Ureterocalicostomy is a well established treatment option in patients who have recurrent ureteropelvic junction obstruction with postoperative fibrosis and a relatively inaccessible renal pelvis. We evaluated the long-term outcome of ureterocalicostomy and factors predicting its failure. MATERIALS AND METHODS: We retrospectively analyzed data on 72 patients who underwent open or laparoscopic ureterocalicostomy from 2000 to 2014. Variables that may affect the outcomes of ureterocalicostomy were assessed with regard to primary pathology findings, patient age, serum creatinine, preoperative renal size (less than and greater than 15 cm), renal cortical thickness (less than and greater than 5 mm), hydronephrosis grade and preoperative renal function (glomerular filtration rate less than and greater than 20 ml/minute/1.73 m2). The surgery outcome was calculated in terms of success or failure. Factors predicting failure were evaluated by univariate and multivariate analysis. Failure was defined as an additional procedure required postoperatively due to persistent symptoms and/or followup renal scan showing persistent significant obstruction with deterioration of renal function on at least 2 occasions 3 months apart. Patients with less than 2-year followup were excluded from study. RESULTS: We analyzed data on 72 patients who underwent ureterocalicostomy during this period. Mean ± SD age of the study group was 28.9 ± 12.3 years and mean baseline serum creatinine was 1.1 ± 0.3 mg/dl. The mean glomerular filtration rate was 27.8 ± 11.6 ml/minute/1.73 m2 and mean cortical thickness of the operated kidney was 7 ± 3.86 mm. Common indications for ureterocalicostomy were failed previous pyeloplasty and/or endopyelotomy in 35 patients (48.6%) and secondary ureteropelvic junction obstruction after pyelolithotomy or percutaneous nephrolithotomy in 24 (33.3%). The most common complication was urinary tract infection, which was seen in 22 patients (30.6%). At a mean followup of 60.3 ± 13.6 months 50 patients (69.5%) had a successful outcome. Treatment failed in 22 patients (30.5%), including 6 who required nephrectomy, while 13 were treated with frequent changes of Double-J® stents or with balloon dilation. In 3 patients ureterocalicostomy was repeated. The rate of failed ureterocalicostomy was higher in patients with a low preoperative glomerular filtration rate (less than 20 ml/minute/1.73 m2), attenuated cortical thickness (less than 5 mm) and higher creatinine (greater than 1.7 mg/dl) on univariate analysis. However, on multivariate analysis poor cortical thickness and a low glomerular filtration rate were independent predictors of failure. CONCLUSIONS: Ureterocalicostomy is an acceptable salvage option with a satisfactory long-term outcome. Patients with a low preoperative glomerular filtration rate (less than 20 ml/minute/1.73 m2) and a thinned out cortex (less than 5 mm) showed a poor outcome after ureterocalicostomy.

Development of a New Outcome Prediction Model in Early-stage Squamous Cell Carcinoma of the Oral Cavity Based on Histopathologic Parameters With Multivariate Analysis: The Aditi-Nuzhat Lymph-node Prediction Score (ANLPS) System.

The aim of this study was to evaluate the histopathologic parameters that predict lymph node metastasis in patients with oral squamous cell carcinoma (OSCC) and to design a new assessment score on the basis of these parameters that could ultimately allow for changes in treatment decisions or aid clinicians in deciding whether there is a need for close follow-up or to perform early lymph node dissection. Histopathologic parameters of 336 cases of OSCC with stage cT1/T2 N0M0 disease were analyzed. The location of the tumor and the type of surgery used for the management of the tumor were recorded for all patients. The parameters, including T stage, grading of tumor, tumor budding, tumor thickness, depth of invasion, shape of tumor nest, lymphoid response at tumor-host interface and pattern of invasion, eosinophilic reaction, foreign-body giant cell reaction, lymphovascular invasion, and perineural invasion, were examined. Ninety-two patients had metastasis in lymph nodes. On univariate and multivariate analysis, independent variables for predicting lymph node metastasis in descending order were depth of invasion (P=0.003), pattern of invasion (P=0.007), perineural invasion (P=0.014), grade (P=0.028), lymphovascular invasion (P=0.038), lymphoid response (P=0.037), and tumor budding (P=0.039). We designed a scoring system on the basis of these statistical results and tested it. Cases with scores ranging from 7 to 11, 12 to 16, and ≥17 points showed LN metastasis in 6.4%, 22.8%, and 77.1% of cases, respectively. The difference between these 3 groups in relation to nodal metastasis was very significant (P<0.0001). A patient at low risk for lymph node metastasis (score, 7 to 11) had a 5-year survival of 93%, moderate-risk patients (score, 12 to 16) had a 5-year survival of 67%, and high-risk patients (score, 17 to 21) had a 5-year survival of 39%. The risk of lymph node metastasis in OSCC is influenced by many histologic parameters that are not routinely analyzed in pathologic reports. These significant independent factors were graded to design a scoring system that permits accurate evaluation of the risk of metastasis with accuracy independent of the traditional TNM system or isolated histologic parameters. The need for neck node dissection can be predicted depending upon the scores obtained.

The importance of microvessel density in predicting cancer progression in patients with penile squamous cell carcinoma.

PURPOSE: To evaluate the role of microvessel density (MVD) in predicting lymph node (LN) metastasis in penile squamous cell carcinoma (PSCC). MATERIALS AND METHODS: Records of 266 patients with PSCC were analyzed. Parameters examined were tumor stage, grade, nodal status, intratumoral and peritumoral MVD. Univariate and multivariate analyses were used to evaluate association between different histopathological variables and MVD. ROC was plotted to derive a prediction model using appropriate cutoff values of the parameters predicting cancer progression. RESULTS: 77 patients were found to have histologically proven metastatic LN. MVD did not correlate significantly with T stage and grade of tumor. The intratumoral and peritumoral MVD of patients with metastatic LN was significantly higher than patients with negative LN (58.92 vs. 49.89 and 65.57 vs. 53.72, respectively; P < 0.0001). Multivariate analysis also revealed that MVD (intratumoral and peritumoral) was independent predictor for LN metastasis. From ROC curve, at the cutoff value of 54, intratumoral MVD predicted LN metastasis with sensitivity of 91% and specificity of 87%. Similarly, at cutoff value of 61, peritumoral MVD predicted LN metastasis with sensitivity of 94% and specificity of 89%. The 5-year survival was 79 and 77% for those with low intratumoral and peritumoral MVD, respectively, as compared to 41 and 39% for those with high intratumoral and peritumoral MVD, respectively (P < 0.05). CONCLUSIONS: Higher intratumoral and peritumoral MVD predicts cancer progression in patients with PSCC. Patients with an intratumoral MVD of 54 and peritumoral MVD of 61 have lymph node metastasis with a high sensitivity and specificity. The overall 5-year survival of patients is poor in high intratumoral or peritumoral MVD.

Outcome of percutaneous nephrolithotomy in anomalous kidney: Is it different?

INTRODUCTION: Various anomalous kidneys such as horseshoe kidney, crossed ectopic kidney, simple ectopic kidney, pelvic ectopic kidney, kidney with duplex system, and malrotated kidney are frequently associated with stone disease. Percutaneous nephrolithotomy (PCNL) is a challenging procedure in these patients because of abnormal orientation of kidney. PATIENTS AND METHODS: Since 2005-2015, 86 patients underwent PCNL for stone removal in anomalous kidneys. Stone characteristics, type of calyceal puncture, number of punctures, need of relook procedures, mean hemoglobin drop, blood transfusion, mean operative time complications, mean hospital stay, stone free rate, and auxiliary procedure were analyzed. RESULTS: Totally 91 sessions of PCNL was done in 86 patients including five of horseshoe kidney who had bilateral stone disease. Mean age, duration of symptoms, stone size, and hospital stay was 29.6 ± 12.6 years, 2.18 ± 1.41 years, 4.40 ± 1.16, and 4.17 ± 2.11 days, respectively. Sixteen patients underwent relook procedure, out of which only 6 could have complete stone clearance. CONCLUSION: PCNL in anomalous kidney is a safe and feasible procedure similar to normally located kidney, but requires careful preoperative planning and intra- and post-operative vigilance.

Outcomes of transurethral resection and holmium laser enucleation in more than 60 g of prostate: A prospective randomized study.

AIM: Transurethral resection of prostate (TURP) is considered a gold standard surgical procedure. The management of benign prostatic hyperplasia (BPH) has undergone tremendous change in recent years and shifted from open to minimal invasive procedure. With the advancement in technology and skills of surgeons, lasers have been used more liberally, particularly holmium laser. Holmium laser enucleation of prostate (HoLEP) is seen as close rival of TURP. The objective if this study is to observe long- and short-term outcomes of transurethral resection and holmium laser enucleation in the prostate of more than 60 g. MATERIALS AND METHODS: This prospective randomized study includes 164 patients. Inclusion criteria were age <75 years after failed or poor response to medical therapy, prostatic size >60 g, gross hematuria secondary to BPH, recurrent urinary tract infection, acute urinary retention, postvoid residual >150 ml, and Schafer Grade II or more. BPH associated with neurogenic bladder, stricture urethra, and carcinoma prostate were excluded from the study. Group 1 comprises patients who underwent TURP and Group 2 comprises who underwent HoLEP. Follow-up was done at 1, 3, 6, 12, and 24 months after the surgery. RESULTS: Data of 144 patients were analyzed. The mean age of patients in TURP and HoLEP group was 66.78 ± 7.81 and 67.70 ± 7.44 years, respectively (P = 0.47), mean prostatic volume was 74.5 ± 12.56 and 75.6 ± 12.84 g, respectively (P = 0.60), operative time was 73.10 ± 10.49 and 89.56 ± 13.81 min, respectively (P = 0.0001). Mean resected tissue was 44.80 ± 9.87 and 48.49 ± 10.87, respectively (P = 0.03). The sexual function did not changed significantly in postoperative follow-up. CONCLUSION: HoLEP is associated with less blood loss, lower transfusion rates, and a shorter hospital stay. The disadvantage of HoLEP is longer operative time and postoperative dysuria.

Intraoperative breakage of Sachse's knife blade: A rare complication of optical internal urethrotomy (one case managing experience)

ABSTRACT Optical internal urethrotomy (OIU) is the most common procedure performed for short segment bulbar urethral stricture worldwide. This procedure most commonly performed using Sachse’s cold knife. Various perioperative complications of internal urethrotomy have been described in literature including bleeding, urinary tract infection, extravasation of fluid, incontinence, impotence, and recurrence of stricture. Here we report a unique complication of breakage of Sachse knife blade intraoperatively and its endoscopic management.

Predictors of successful trial without catheter following acute urinary retention in benign prostatic enlargement: A single centre, multivariate analysis.

OBJECTIVE: To evaluate the parameters which predict the success or failure of trial without catheter (TWOC) for acute urine retention (AUR). MATERIALS AND METHODS: Medical records of 2 188 patients presenting with first episode of AUR were analyzed. All patients underwent catheterization and were started on α-blocker followed by TWOC. Age, baseline American urological association (AUA) score, prostate volume (PV), residual volume of urine (RV) and intravesical prostatic protrusion (IPP), prostate specific antigen (PSA) were recorded. RESULTS: TWOC was successful in 737 patients (33.7%) and failed in 1 451 patients (66.3%). Patients with successful TWOC had lower mean age, PV, IPP, RV, AUA score, and PSA than those with failed TWOC. On multivariate analysis, the significant independent predictors were IPP, age, AUA score, PV, and RV at odds ratios of 3.11, 1.84, 1.78, 1.53, and 1.23, respectively. From ROC curve, IPP had cut off value of 9 mm and detected success of TWOC with sensitivity (S) of 91% and failure with specificity (s) of 90%. Similarly, cut off value of 64 years for age (S:86%, s:87%), 20 for AUA symptom score (S:83%, s:81%), 56 cc for PV (S:80%, s:74%) and 750 mL for RV (S:71%, s:68%) were obtained. CONCLUSION: Age, baseline AUA score, IPP, PV, and RV independently predict the outcome of TWOC. Patients with IPP > 9 mm, age > 65 years, baseline AUA score > 20, PV > 56 cc, or RV > 750 mL have less probability of successful TWOC in AUR and can be considered for immediate surgery following an episode of AUR.
