RESUMEN
INTRODUCTION: The aim of the study is to evaluate the clinical efficacy of Triple-D scoring system versus Quadruple-D scoring system for assessing stone-free rate (SFR) in individuals with renal stones measuring 1-2 cm in diameter after extracorporeal shock wave lithotripsy (ESWL). MATERIALS AND METHODS: The study was conducted on 120 patients who presented to a tertiary care center in eastern India. Systemic random sampling technique was applied with a sampling interval of 2. Triple-D scoring system comprising of three computed tomography based metrics - stone dimension (volume), stone density (Hounsfield unit), and skin-to-stone distance (SSD) was done before ESWL. Stone location was included as an additional parameter to formulate Quadruple-D scoring system where an extra score was given for stones in the non-lower polar region. Stone-free status was assessed by plain abdominal radiography 3 weeks after ESWL. RESULTS: In the study population, stone dimension, stone density, and stone location were positive predictors of SFR after ESWL whereas age, sex, and body mass index of the patients, laterality of the stone and SSD were not. The area under the curve of Triple-D and Quadruple-D scoring systems were 0.598 and 0.674. CONCLUSION: Triple-D scoring system has been successfully validated as the SFR showed a parallel increase with every positive component. The Quadruple-D scoring system with a simple addition of stone location can further facilitate the validation of Triple-D scoring by increasing SFR, keeping the calculation simple and easy to use. These findings support the incorporation of Quadruple-D scoring system over Triple-D scoring system.
RESUMEN
Periurethral lesions are common in post-menopausal women. The differential diagnosis includes urethral caruncle, urethral prolapse, urethral diverticulum and the notorious urethral malignancy. Non-invasive squamous lesion of the urethra is rare with limited data on clinical significance. We present a case of urethral squamous papilloma in a premenopausal woman causing significant storage and voiding symptoms.
RESUMEN
BACKGROUND: Partial nephrectomy has emerged as a standard treatment for small renal masses offering oncologic control equivalent to radical nephrectomy, with preservation of renal function and evidence for equivalent survival. In this study, we evaluated RENAL nephrometry score (RNS) in predicting perioperative outcomes in patients with partial nephrectomy. MATERIALS AND METHODS: This was a prospective observational study conducted from February 2016 to August 2017 which included patients who underwent partial nephrectomy. The patients were divided into three groups depending on the complexity scores (low, moderate, and high). Tumors were assigned RNS and tumor-node-metastasis staging of the clinically malignant tumors was done. Blood loss, warm ischemia time (WIT), and surgical complications were assessed. RESULTS: A total of 20 patients underwent open partial nephrectomy during the study. There were 4 (20%) low, 11 (55%) moderate, and 5 (25%) high-complexity lesions. Blood loss was significantly different in three groups. All the cases in high-complexity group were performed with clamping the renal vessels with a mean WIT of 29 min. The overall complication rates were significantly different between the groups (P = 0.007); however, majority of the complications were low grade (Grades I and II) and were managed conservatively. CONCLUSION: In the present study, RNS was correlated with predicting surgical access route, need for clamping during partial nephrectomy, blood loss, decrease in glomerular filtration rate of operated kidneys, postoperative complications, and tumor grade.
RESUMEN
CONTEXT: Analgesia during extracorporeal shockwave lithotripsy for renal stone is an essential component. It not only makes the procedure comfortable but also increases the stone-free rate. AIMS: The aim of this study was to evaluate the efficacy of triple oral analgesic agents on stone fragmentation and pain relief in comparison to injectable analgesic agents. SETTINGS AND DESIGN: This prospective randomized study included 68 patients of renal calculi of size 5-15 mm. SUBJECTS AND METHODS: Group A had 32 patients, who received injection pentazocine and injection diclofenac, 45 min before the procedure. Group B consisted of 28 patients, who received a combination of oral acetaminophen, 325 mg, oral diclofenac 50 mg, and oral tramadol 37.5 mg, 45 min prior. Procedural findings, pain score visual analog scale (VAS), fragmentation rate, and outcome were recorded. STATISTICAL ANALYSIS USED: Independent t-test and Pearson's correlation test. RESULTS: A total of 60 patients were analyzed. The mean age was 40.2 ± 11.8 years. Both groups were comparable in body mass index, stone size, number, and density. Group A required more shocks than Group B (4274 vs. 3693, P = 0.043). A lower energy level of shocks (kV) was tolerated in Group A (2.5 vs. 3.2, P = 0.002). Group A required more sittings than Group B (2.3 vs. 1.9, P = 0.037). VAS score was significantly less in Group B (2.9 vs. 4.9, P = 0.0001). The overall fragmentation rate was similar among groups (81.2% vs. 89.3%); hence, the successful outcome was (59.4% vs. 75.0%, P = 0.274). The occurrence of adverse events was also equivalent in both groups (P = 0.199). CONCLUSIONS: Triple oral regime provides better analgesic effect and quicker stone-free rate than injectable agents but with similar final outcome.
RESUMEN
PURPOSE: To assess the role of serum Cystatin C, IL-18 and Uric acid in acute kidney injury (AKI) in urological patients, along with their prognostic significance. MATERIALS AND METHODS: Prospective observational study included 61 cases, admitted in urology ward with baseline serum creatinine ≤1.5â¯mg/dL. All patients had at least one or more predisposing factors for AKI. Daily urine output and creatinine level were checked. Serum levels of biomarkers were measured at baseline and postoperatively after 24â¯h. Development of AKI and its outcome were analysed. RESULTS: Thirty nine patients (63.9%) developed AKI in the study. Patients with AKI were found to have a greater percentage rise of Cystatin C (118.7% v/s 81.8%, pâ¯=â¯0.005), IL-18 (59.0% v/s 25.5%, pâ¯=â¯0.004) and Uric acid (34.3% v/s 19.2%, pâ¯=â¯0.008) after 24â¯h. Absolute Uric acid level at day 1 was also significantly associated with AKI (5.18⯱â¯0.91 v/s 4.45⯱â¯0.86, pâ¯=â¯0.003). Risk stratification of AKI was poor for all biomarkers. Area under curve for Cystatin C, IL-18 and Uric acid was 0.715, 0.696 and 0.734 respectively. Renal function after 3â¯months, had a positive correlation with baseline creatinine and baseline Cystatin C levels (râ¯=â¯0.56 & 0.39). CONCLUSIONS: Postoperative serum Cystatin C, IL-18 and Uric acid after 24â¯h were significantly associated with AKI. Baseline Cystatin C had moderate capability to predict short term renal function.

Primary Urethral Carcinoma (PUC) is considered as a rare tumour, accounts for less than 1% of all malignancies and an incidence rate of four cases per million patients. Incidence increases with the patient's age and most commonly present in seventh decades. Urothelial carcinoma is the most common type (76%) of the PUC, adenocarcinoma accounts for less than 5% of the PUC. No definitive protocol for tumour management for urethral adenocarcinoma has been described in the literature due to lack of prospective study and scarcity of the cases. Treatment usually depends on the site and stage of the tumour. We hereby report a case of 33-year-old male patient with urethral adenocarcinoma of bulbomembranous urethra spread to the prostatic urethra and left side inguinal lymph node. He was treated through multimodal therapy with surgery plus adjuvant chemotherapy.

Pyonephrosis is a suppurative infection of upper urinary tract due to obstruction of the ureter. It is usually associated with suppurative damage of renal parenchyma and renal function loss. Patients are mostly symptomatic but may remain asymptomatic in 15% of cases. Severe infection in pyonephrosis may lead to urosepsis and may endangered life, if timely not treated with surgical intervention. We hereby report a rare case of Giant Pyonephrosis (GP), contained 11 liters of pus, due to Ureteropelvic Junction (UPJ) obstruction presented with haematuria. The patient was treated with open nephrectomy. The aetiology, clinical features, diagnosis and management of pyonephrosis with the review of literature of GP in the background of a rare case report have been discussed here.
RESUMEN
The ureterocele is an uncommon congenital anomaly of the lower ureter. Ureterocele with a single pelvicalyceal system, bilateral, and orthotopic variety is less common. Calculi within bilateral ureterocele are a rare occurrence. To the best of our knowledge, only a few similar cases have been reported in the literature. Among the all reported presentations of this type of ureterocele, presentation with Acute Urinary Retention (AUR) has not been described in the literature. We present a case of nine-year-old child having bilateral, single system orthotopic ureterocele with calculi in bilateral ureterocele and presented with AUR due to obstructive bulbar urethral calculus. The bilateral endoscopic incision was given and all four calculi were removed endoscopically through percutaneous route. Voiding cystourethrography after two years follow-up was non-refluxing. The purpose of reporting this case is the rarity of the disease and to emphasize that delay in diagnosis and treatment of these cases may lead to complications such as recurrent urinary tract infection and renal failure.
RESUMEN
PURPOSE: Extracorporeal shock wave lithotripsy (ESWL) is an established modality for renal calculi. Its role for large stones is being questioned. A novel model of temporary double J (DJ) stenting followed by ESWL was devised and outcomes were assessed. MATERIALS AND METHODS: The study included 95 patients with renal calculi sized 1 to 2 cm. Patients were randomized into 3 groups. Group 1 received ESWL only, whereas group 2 underwent stenting followed by ESWL. In group 3, a distinct model was applied in which the stent was kept for 1 week and then removed, followed by ESWL. Procedural details, analgesic requirements, and outcome were analyzed. RESULTS: Eighty-eight patients (male, 47; female, 41) were available for analysis. The patients' mean age was 37.9±10.9 years. Stone profile was similar among groups. Group 3 received fewer shocks (mean, 3,155) than did group 1 (mean, 3,859; p=0.05) or group 2 (mean, 3,872; p=0.04). The fragmentation rate was similar in group 3 (96.7%) and groups 1 (81.5%, p=0.12) and 2 (87.1%, p=0.16). Overall clearance in group 3 was significantly improved (83.3%) compared with that in groups 1 (63.0%, p=0.02) and 2 (64.5%, p=0.02) and was maintained even in lower pole stones. The percentage successful outcome in groups 1, 2, and 3 was 66.7%, 64.5%, and 83.3%, respectively (p=0.21). The analgesic requirement in group 2 was higher than in the other groups (p=0.00). Group 2 patients also had more grade IIIa (2/3) and IIIB (1/2) complications. CONCLUSIONS: Stenting adversely affects stone clearance and also makes the later course uncomfortable. Our model of brief stenting followed by ESWL provided better clearance, comfort, and a modest improvement in outcome with fewer sittings and steinstrasse in selected patients with large renal calculi.

INTRODUCTION: Several minimally invasive approaches are available for the treatment of bladder stones, with each having its own advantages and disadvantages. We devised a new technique to overcome a few limitations of conventional techniques and compared its efficacy with conventional percutaneous cystolithotripsy (PCCL) technique. MATERIAL AND METHODS: This was a randomized, open-label, prospective, controlled study conducted from July 2015 to December 2016 that included 62 patients with bladder calculus of ≥2 cm in size. Patients were randomly assigned into two groups. Patients from Group 1 were treated with new a technique using a transurethral nephroscope via resectoscope outer sheath and patients from Group 2 were treated with conventional PCCL. RESULTS: Overall, the mean (SD) age was 53.3 (11.4) years and 49.9 (12.8) years for Group 1 and 2, respectively; and stone size was 3.2 (0.8) and 3.2 (0.7), respectively. Operative time was similar in both groups (32.7 [8.7] versus 34.3 [7.0]; P = 0.428). The length of hospital stay was higher in Group 2 (2.1 [0.4]) as compared to Group 1 (1.2 [0.5]) (P = 0.000). Stones were completely cleared in all patients.Group 2 patients required more analgesics and had more complications like hematuria and wound infection. CONCLUSIONS: Results showed that cystolithotripsy with nephroscope via resectoscope sheath is an alternative to the conventional PCCL techniques as the new technique was associated with lesser complications, better cosmetic outcome and minimal analgesic requirement.
RESUMEN
CONTEXT: Relook transurethral resection of bladder tumor (TURBT) improves the diagnostic and therapeutic efficacy of primary TURBT. However, it is still not established as to which category of patients would benefit most from this repeat invasive procedure. AIMS: This prospective interventional study was designed to identify the category of patients with non-muscle invasive bladder cancer who may benefit from a routine relook procedure. SETTING AND DESIGN: A total of 52 consecutive patients with biopsy proven non muscle invasive bladder cancer on primary TURBT underwent a relook TURBT between March 2011 and September 2012. MATERIALS AND METHODS: The incidence of residual tumor and tumor upstaging on relook procedure was correlated with various histopathological (stage, grade, CIS, presence of muscle) and cystoscopic (type and focality of tumor, any apparent field change) parameters on primary TURBT. RESULTS: Out of the total 52 patients, 23 (44.2%) had a residual tumor on relook TURBT. 12 (23.1%) were upstaged (of these 9 i.e. 17.3% to muscle invasion). While most of the parameters studied showed a positive correlation with incidence of residual tumor and upstaging to muscle invasion, statistical significance (for both) was reached only for tumor stage (P = 0.028 and 0.010), tumor grade (P = 0.010 and 0.002) and tumor type (solid vs. papillary; P = 0.007 and 0.001). Carcinoma in situ showed a significant correlation with incidence of residual tumor (P = 0.016) while the absence of muscle in the primary TURBT specimen was significantly associated with upstaging to muscle invasive disease (P = 0.018). STATISTICAL ANALYSIS: The data was analyzed using SPSS software v. 16.0. CONCLUSIONS: Relook TURBT may be especially recommended for high grade and T1 tumors and tumors with a solid/sessile appearance on primary TURBT especially when deep muscle was absent in the primary TURBT specimen.
RESUMEN
The optimal upper limit of the normal range for prostate specific antigen (PSA) is suggested, but review of literature reveals that, malignancy of prostate can occur below that range and some benign prostatic diseases are occasionally associated with higher levels. The aim of the study is for early detection of prostatic malignancy. We tried to evaluate digital rectal examination (DRE), estimation of PSA and transrectal ultrasound (TRUS) guided core needle biopsy and histopathological examination in the patients. Seventy-two consecutive patients with lower urinary tract symptoms were taken in this retrospective study from January 2005 to February 2006. PSA level was measured by automated chemilumininescence system. Prostatic biopsies were taken for histopathological examination and stained with haematoxylin and eosin. Gleason grading was applied in case of adenocarcinoma of prostate. For detection of malignancy, sensitivity, specificity, predictive value for positive test and of negative test, percentage of false negatives and false positives, p-values, confidence interval and kappa statistical calculations were done. It was found 19 cases with PSA level > 4 ng/ml had benign diseases of prostate and one person having PSA level < 4 ng/ml had adenocarcinoma of prostate. Seven DRE positive cases had benign disease of the prostate and 5 DRE negative patients had adenocarcinoma of prostate. When compared, serum total PSA value alone and combined PSA and DRE, the later combined approach was found to be more useful. We recommend the study of DRE, PSA and TRUS guided core needle biopsy for detection of prostatic cancer at localised and potentially curable stage.
