RESUMEN
BACKGROUND: Renal artery pseudoaneurysm following partial nephrectomy is a rare entity, the incidence of this entity is more common following penetrating abdominal injuries, percutaneous renal interventions such as percutaneous nephrostomy(PCN) or Percutaneous nephrolithotomy (PCNL). Although rare, renal artery pseudoaneurysm can be life threatening if not managed timely, they usually present within two weeks postoperatively with usual presenting complains being gross haematuria, flank pain and/or anaemia. CASE PRESENTATION: We report case of two female patients 34 and 57 year old respectively of South Asian ethnicity, presenting with renal artery pseudoaneurysm following left sided robot assisted nephron sparing surgery for interpolar masses presenting clinically with total, painless, gross haematuria with clots within fifteen days postoperatively and their successful treatment by digital subtraction angiography and coil embolization. CONCLUSION: Renal artery aneurysm is a rare fatal complication of minimally invasive nephron sparing surgery however considering the preoperative and intraoperative risk factors for its development and prompt suspicion at the outset can be life saving with coil embolization of the bleeding arterial aneurysm.

INTRODUCTION: Prostate-specific antigen (PSA) is a reliable biomarker for identification of prostate cancer, although a biopsy is still the gold standard for detecting prostate cancer. Similar to higher PIRADS lesions on MRI, the maximal standard uptake value (SUV max) on PSMA PET is linked to a higher likelihood of prostate cancer. Can an mpMRI in conjunction with PSMA PET Scan accurately predict prostate cancer and further trigger omission of biopsy similar to other solid organ urological malignancies? METHODS: Ga-68 PSMA PET and mpMRI were performed for each patient who was a part of this retrospective study. The PET-positive lesion's maximum standardized uptake value (SUVmax) was recorded. Prostate biopsies were performed on patients who had PSMA PET avid lesions and a PIRADS score of 4 or 5. Robot-assisted radical prostatectomy (RARP) was afterward performed on patients who had cancer on their prostate biopsy. The prostatectomy specimen's histopathological information was recorded. Cutoff values and correlations between the variables were determined using the ROC curves and Pearson's correlation test. RESULT: On the basis of suspicious DRE findings or elevated PSA, 70 men underwent mpMRI and PET scans. PIRADS 4 patients had a median (IQR) SUVmax of 8.75 (11.95); whereas, PIRADS 5 patients had an SUVmax of 24.5 (22). The mean SUVmax for patients whose biopsies revealed no cancer was 6.25 ± 1.41. With an AUC of 0.876 on the ROC curve, it was found that there was a significant positive correlation between the results of the mpMRI and PET scans and those of the histopathological investigation. A SUVmax ≥ 8.25 on PSMA PET for a PIRADS 4/5 lesion on mpMRI will aid in correctly predicting malignancy, with a sensitivity of 82.8% and specificity of 100%. CONCLUSION: The findings of this study were positive and indicated that patients with a high suspicion of prostate cancer on mpMRI and PSMA PET (PIRADS ≥ 4 and SUVmax ≥ 8.25). This study substantiates the fact that a combination of mpMRI and PSMA PET can accurately predict localized prostate cancer.
RESUMEN
Introduction: Multiple studies have been published recently assessing feasibility of robot-assisted partial nephrectomy (RAPN) for moderate to highly complex renal masses. Some studies have even compared partial nephrectomy (PN) performed through various modalities such as open PN (OPN) versus RAPN and laparoscopic PN (LPN) versus OPN. The primary aim of this review was to analyze perioperative outcomes such as warm ischemia time (WIT), duration of surgery, estimated blood loss (EBL), complications, blood transfusion, length of stay, and margin status following RAPN for complex renal masses. Another objective was to compare perioperative outcomes following various surgical modalities, i.e., OPN, LPN, or RAPN. Methods: Literature search was conducted to identify studies reporting perioperative outcomes following RAPN for moderate (Radius, Endophytic/Exophytic, Nearness, Anterior/posterior location [RENAL] score 7-9 or Preoperative Aspects of Dimension used for anatomic classification [PADUA] score 8-9) to high complexity renal masses (RENAL or PADUA score ≥ 10). Meta-analysis of robotic versus OPN and robotic versus LPN was also performed. Study protocol was registered with PROPSERO (CRD42019121259). Results: In this review, 22 studies including 2,659 patients were included. Mean duration of surgery, WIT, and EBL was 132.5-250.8 min, 15.5-30 min, and 100-321 ml, respectively. From pooled analysis, positive surgical margin, need for blood transfusion, minor and major complications were seen in 3.9%, 5.2%, 19.3%, and 6.3% of the patients. No significant difference was noted between RAPN and LPN for any of the perioperative outcomes. Compared to OPN, RAPN had significantly lower EBL, complications rate, and need for transfusion. Conclusions: RAPN for moderate to high complexity renal masses is associated with acceptable perioperative outcomes. LPN and RAPN were equal in terms of perioperative outcomes for complex masses whereas, OPN had significantly higher blood loss, complications rate, and need for transfusion as compared to RAPN.
RESUMEN
PURPOSE: Transurethral resection of bladder tumor is the standard of care for the management of patients with bladder mass. Primary objective of this study was to compare safety and efficacy of the two energy modalities used for TURBT (monopolar and bipolar). MATERIALS AND METHODS: Systematic literature search of various electronic databases was conducted to include all the randomized studies comparing two groups. Standard PRISMA (Preferred reporting Items for Systematic reviews and Meta-analysis) guidelines were pursued for this review and study protocol was registered with PROSPERO (CRD42019139987). RESULTS: In the present review, eight RCTs including 1147 patients were included. Resection time, hospital stay and catheter duration were significantly shorter with bipolar group. There was no significant difference in incidence of obturator reflex (OR 0.65, CI [0.35, 1.2], p = 0.17), whereas incidence of bladder perforation was significantly higher in the monopolar group (6.4% versus 3.3%, p = 0.01. However, sensitivity analysis including 3 high quality studies revealed equal incidence of bladder perforations. Need for blood transfusion was similar in the two groups but fall in hemoglobin was significantly lower in bipolar group (MD - 0.45 CI [- 0.72, - 0.18], p = 0.0009). Bipolar group was found to have significantly lower incidence of tissue artifacts due to thermal energy on pathological examination (OR 0.27 CI [0.15, 0.47], p < 0.00001). CONCLUSIONS: Bipolar and monopolar devices are equally safe in terms of obturator jerk and bladder perforation. Bipolar group was significantly better as compared to monopolar for hospital stay, catheter duration and fall in hemoglobin; however, the clinical relevance of most of these parameters is little.

Large renal aneurysms can masquerade as simple renal cysts on ultrasound, especially if Doppler examination is not routinely done to assess flow characteristics. We present a case report of a 26-year-old male, as a clinical challenge in urology, who had minimal symptoms, yet had an arteriovenous fistula with a large aneurysm which was diagnosed as a parapelvic cyst on ultrasound. Endovascular treatment of the arteriovenous fistula was done using a vascular plug with satisfactory outcomes.

OBJECTIVE: To share our experience and techniques of robot-assisted repair of complex vesicovaginal fistulae. METHODS: Prospectively maintained data of patients undergoing robot-assisted repair of complex vesicovaginal fistula (VVF) from December 2014 to October 2019 were analyzed. Patient characteristics, operative data, postoperative events, and follow-up outcomes were noted. All cases underwent preoperative cysto-vaginoscopy and upper tract imaging. The procedure was completed in a standard fashion. Additional procedures included Boari flap reimplantation, Burch-colposuspension, ureteric reimplantation and Vaginal flap incorporation. On follow-up, successful repair was defined as no urine leak after removal of catheter. RESULTS: Out of 73 patients undergoing robot-assisted VVF repair at our institute, 33 were classified as complex VVF. Mean age was 42.7 ± 7.2 years. The most common cause of VVF was posthysterectomy (81.8%) with 21 (63.1%) recurrent VVFs. Thirty patients (90.0%) had supratrigonal fistulae; multiple fistulae were present in 3 cases. Two patients underwent Boari flap ureteric reimplantation for concomitant ureteric stricture and ureteric neocystostomy was required in another patient. One patient underwent our novel technique of vaginal flap incorporation and a Burch colposuspension was performed simultaneously in one patient with stress incontinence. The median follow-up was 35 months (interquartile range 8.5months). Successful outcome was noted in 31 (93.9%) patients; recurrence requiring further repair in 2 patients. CONCLUSION: The current series presents the largest number of complex VVFs repaired by robotic assistance. Robot-assisted repair can be considered as one stop procedure for such complex and vexing problems.

INTRODUCTION: Penile fracture is a rare urological emergency, best managed by early surgical intervention, but the data on subsequent sexual function is sparse. This study was designed to analyze the clinical spectrum and sexual function after penile fracture repair at our tertiary care center. MATERIALS AND METHODS: Ambispective observational study was undertaken from July 2002 to August 2019 which included patients admitted with a history of trauma to the penis in the erect state. The clinical presentation, etiology and the details of the surgical management were noted. Patients were contacted telephonically and were called for follow-up. They were evaluated for the presence of penile nodules or curvature, and the erectile function was objectively recorded using the Sexual Health Inventory for Men (SHIM) questionnaire and the Erection Hardness Score (EHS). RESULTS: Median age at injury was 37 years, and injury during the sexual intercourse (33/43) was the most common etiology. Five patients presented with blood at the meatus. Ultrasound was performed in 27 patients and could detect the injury with a 55% sensitivity. All but one case were repaired through a subcoronal degloving incision. At a median follow-up of 36 months, follow-up data of 20 patients were available. Of the 20 patients, 14 were sexually active. The mean SHIM score was 21.36 ± 1.33 and the mean EHS was 3.21 ± 0.43. Four of the 20 patients developed penile nodule while 2 of them had penile curvature which was not bothersome. CONCLUSION: Penile fracture remains primarily a clinical diagnosis. Although prompt diagnosis and an emergent surgical exploration provides good outcomes in terms of preservation of erectile function, patients should be apprised about the problems of penile nodule and curvature.
RESUMEN
AIMS: Actinium-225 (225Ac) labeled prostate-specific membrane antigen (PSMA)-617 is a novel treatment modality in the management of metastatic castration-resistant prostate cancer (mCRPC). The present study was conducted to assess the impact of 225Ac-PSMA-617 therapy on the quality-of-life of patients with heavily pretreated mCRPC using the National Comprehensive Cancer Network-Functional Assessment of Cancer Therapy-Prostate Symptom Index-17 (NCCN-FACT-FPSI-17) questionnaire. MATERIALS AND METHODS: This was a retrospective single-center study where data of consecutive heavily pretreated mCRPC patients treated with 225Ac-PSMA-617 from January 2019 to February 2020, was collected and analyzed for the biochemical response, quality-of-life outcomes and treatment-related toxicity. RESULTS: Eleven heavily pretreated mCRPC patients received a median cumulative dose of 8.3 MBq (interquartile range [IQR] 5.6-20.4 MBq) 225Ac-PSMA-617 over 1-4 cycles. 5/11 patients (46%) showed a ≥50% decline in Prostate Specific Antigen (PSA), while stable values and PSA progression were observed in 3/11 (27%) patients each. Pre- and post-therapy NCCN-FACT-FPSI-17 questionnaires revealed statistically significant improvement in the total FPSI score (P = 0.003) as well as the disease-related symptoms-physical (P = 0.004) and disease-related symptoms-emotional (P = 0.046) subscores. Among the physical symptoms, significant improvement was noted with respect to pain, difficulty in urination, bone pain, fatigue, and restriction in physical activity. No significant change was noted in the treatment side-effects subscore. Of the treatment-related adverse effects, Grade 3 dryness of the mouth, anemia, and nephrotoxicity was observed in 1/11 patients (9%) each and Grade 3 thrombocytopenia in 2/11 patients (18%). CONCLUSION: Health-related quality-of-life of the mCRPC patients improved significantly with 225Ac-PSMA-617 despite extensive pretreatment and advanced nature of the disease.
RESUMEN
PURPOSE: Stent-related symptoms are frequent following stent placement for various indications. Use of PDE inhibitors has expanded beyond their classical indication and has been tried in patients with stent-related symptoms. The systematic review was conducted to ascertain the efficacy of PDE inhibitors in ameliorating stent-related symptoms. METHODS: We performed systematic review and metanalysis on the use of PDE inhibitors for stent-related symptoms in patients who underwent stent placement for various reasons (postpercutaneous nephrolithotomy or ureterorenoscopy). We followed PRISMA guidelines while conducting this review and study protocol was registered with PROSPERO (CRD42019121781) RESULTS: Three studies with 280 participants were included in this review. There was considerable heterogeneity across all the outcome parameters assessed; thus, random-effect model was used for analysis. Comparison of PDE inhibitors with control arm revealed that PDE inhibitors were significantly more effective than placebo in all but one domain (Work performance) of the USSQ. On comparison with alfa blockers, PDE inhibitors were found to be equally effective for urinary symptoms, general health, and body pain parameters, but sexual health parameters improved significantly with PDE inhibitors. CONCLUSION: PDE inhibitors can be considered an option for patients with stent-related symptoms especially in patients with sexual dysfunction. Due to various limitations of the studies included in this review, we recommend conducting further high-quality studies.

INTRODUCTION: Transurethral resection of bladder tumor (TURBT) aims at complete resection of all the visible tumors. Existing guidelines recommend restage TURBT in all patients with T1 and high-grade tumors, to avoid under-staging. However, restage TURBT may not be plausible/feasible at all the times. This study was performed with an aim to better define the utility of restage TURBT in a tertiary care hospital of India. METHODS: Patients with high grade/T1 tumors at the first TURBT were prospectively enrolled. Their demographic profile, previous cystoscopic findings, and histological reports were recorded. The primary objective was to assess the tumor detection and stage up-migration rates at restage TURBT. The secondary objectives was to identify factors predicting presence of tumor at restage TURBT. Patients were followed up to detect recurrence and progression for a minimum of 3 months. RESULTS: Of 128 prospective patients' enrolled, 29 patients were lost to follow-up and 11 patients did not undergo restage. A total of eighty-eight patients underwent restage TURBT of which twenty-eight patients (31.8%) had tumor at their second TURBT with five of these patients being upstaged to T2. The risk of having a tumor at restage was significantly higher in patients with solid tumors (56.2% vs. 26.4%, P = 0.02, 95% confidence interval: 0.035-0.024) but was independent of the tumor size (P = 0.472), number of growths (P = 0.267), grade of tumor (P = 0.441), presence or absence of muscle at the initial TURBT (P = 0.371) and place of initial TURBT (P = 0.289). There was a significant difference in the recurrence and progression rates in patients who had tumor at restage as compared to those who did not (recurrence; 33.3% and 23.8%, P = 0.022, respectively vs. progression; 11.1% and 3.7% respectively, P = 0.07; mean follow-up = 10.8 months). CONCLUSIONS: We conclude that restage TURBT is necessary in patients with solid looking tumors and the presence of tumor at restage confers a higher risk of recurrence and progression.
RESUMEN
With the emergence of recent landmark trials, the treatment for hormone-sensitive metastatic prostate cancer (hsMPC) is changing from androgen deprivation therapy (ADT) alone to combination therapy. Both, docetaxel chemotherapy and abiraterone in addition to ADT have been extensively studied in well-conducted randomized controlled trials and were shown to improve outcomes. However, this paradigm shift in the treatment has also raised some queries. This mini review reflects upon the four landmark trials and tries to provide some perspective about the decision-making process for the patients with hsMPC.
RESUMEN
The transitional zone is the most common site of benign prostatic hyperplasia (BPH). Exophytic BPH is an exceedingly rare entity with only one case described in the English literature. We herein describe a case of exophytic BPH in a 48-year-old man presenting as a large pelvic mass with refractory retention managed successfully with robot assistance. To the best of our knowledge, this is the first case of exophytic benign prostatic enlargement managed by surgical excision.
RESUMEN
INTRODUCTION: Open radical cystectomy (RC) is associated with significant morbidity and the role of minimally invasive surgery (MIS) in reducing morbidity of RC is controversial A direct comparison of various surgical modalities on perioperative outcomes is lacking in the Indian literature. We evaluated outcomes of minimally invasive (robotic and laparoscopic) versus open RC with pelvic lymph node dissection (PLND) performed at our institute from 2014 to 2016. METHODS: Eighty-three patients of RC with PLND were prospectively analyzed from December 2014 to February 2016. All patients of muscle invasive urothelial cancer of the bladder undergoing RC (open or MIS) were included in the study. Based on patients preference they were assigned to one of the three groups (Open RC, robot-assisted RC, or laparoscopic RC). Their demographic profile, preoperative disease stage, operative data like operative time, blood loss, intraoperative complications, histopathological data like pathological stage, lymph-node yield etc., postoperative complications if any and total duration of stay were recorded. These data of laparoscopic, open, and robotic cystectomies were compared in terms of various demographic, histopathologic parameters and perioperative outcomes. RESULTS: Twenty-nine patients (34.93%) underwent minimally invasive RC with PLND (5 laparoscopic and 24 robotic). The median age of patients was 58 years. Mean number of lymph nodes removed was 22.5 ± 14.6. The total number of lymph nodes removed in laparoscopic surgery was 104 with a yield of 20.6 per patient, in robotic surgery were 627 with a yield of 26.1 per patient, and in open surgery were 1119 with a yield of 20.7 per patient (P = 0.004). Clavien-Dindo Grade 2 and 3 complications were seen in 37.5% of robotic, 60% of laparoscopic, and 55.54% of open RC. Average blood loss and operative time in laparoscopic, robotic, and open RC were 511.53 ± 311.02 ml, 552.08 ± 267.63 ml, and 512.05 ± 213.9 ml and 8.23 ± 1.36 h (hrs), 7.53 ± 1.92 h, and 5.85 ± 1.76 h, respectively (P = 0.68 and <0.001, respectively). CONCLUSIONS: MIS is associated with significantly longer operative time than open RC. Robotic RC has significantly higher lymph node yield than open or laparoscopic RC. Minimally invasive RC is equivalent to open surgery in terms of perioperative morbidity, mortality, and blood loss.
RESUMEN
INTRODUCTION AND OBJECTIVE: The RENAL, PADUA and centrality index (C-index) nephrometry scoring systems (SS) have been individually evaluated for their role in predicting trifecta outcomes after nephron-sparing surgery (NSS). However, there is little data on their comparative superiority. The present study was designed to evaluate the predictive value of three SS and to assess interobserver reliability. MATERIALS AND METHODS: Fifty patients undergoing NSS at our center between January 2014 and April 2016 were included in the study. The demographic details were noted. Images (computed tomography [CT] scans or magnetic resonance imaging) were reviewed by a urologist and a radiologist independently and RENAL, PADUA, and C-index were calculated. The correlation between these scoring system and trifecta outcomes were calculated. RESULTS: The RENAL and PADUA score did not correlate with any of the perioperative parameters. However, C-index had a significant correlation with operative time (OT) (P = 0.02) and trifecta outcomes (P < 0.05). There was an excellent concordance between the two observers in scoring the RENAL score (α = 0.915; intraclass correlation coefficient [ICC] = 0.814) and PADUA score (α = 0.816; ICC = 0.689 [P < 0.001]). There was lesser although acceptable concordance in the calculation of C-index (ICC -0.552; α -0.711). CONCLUSIONS: There is good correlation among all the 3 SS. C-index has lower reproducibility due to difficult mathematical calculation but correlated best with trifecta outcomes.
RESUMEN
We report three cases of renal cell carcinoma (RCC) associated with abscess formation. Such association has been reported uncommonly in literature. Our cases were unique in that final histopathological report was papillary RCC in all of the patients.
RESUMEN
A lost needle during minimally invasive surgery is a cause of undue anxiety to the entire surgical team and also causes prolongation of surgical time. There is no literature reporting follow-up of any patient with needle left behind as they are considered as a 'never event' during a surgical procedure. Preventing such events needs vigilance on part of the surgeon and assistant. Here, we report a case of lost needle during performance of a robot-assisted nephron sparing surgery. The robot needed to be de-docked and converted to laparoscopy. After a thorough search, the needle was found to be lodged at an unusual place. A brief review of available literature is also provided alongside.

Penile gangrene is very rare sequel of ischemic priapism. Previous published reports have shown its occurrence in patients with sickle cell disease, urethral carcinoma, bladder carcinoma, thrombotic thrombocytopenic purpura, idiopathic, traumatic, etc. Ischemic priapism with penile gangrene as an initial presentation of multiple myeloma has not been reported. We present a 44-year-old patient of multiple myeloma presenting with ischemic priapism and penile gangrene requiring partial penectomy.
RESUMEN
PURPOSE: This study aims to determine the pre-biopsy diffusion-weighted imaging (DWI) and magnetic resonance spectroscopic imaging (MRSI) characteristics of patients with high-grade prostatic intraepithelial neoplasia (HGPIN) and perform follow-up studies in these patients to assess the clinical implications. MATERIALS AND METHODS: One hundred sixteen men with prostate specific antigen between 4 and 10ng/ml underwent pre-biopsy MR examinations. Nine of them had HGPIN lesions without concomitant prostate cancer (PCa) on biopsy. Apparent diffusion coefficient (ADC) and metabolite ratio [Citrate/(Choline+Creatine)] were calculated and these 9 patients were followed to determine the clinical outcomes. RESULTS: Mean ADC for HGPIN foci was 1.01±0.16×10(-3)mm(2)/s while for the normal peripheral zone it was 1.69±0.25×10(-3)mm(2)/s (p<0.005). Mean metabolite ratio for voxels in the HGPIN region of initial biopsy was 0.24±0.16 while for the normal peripheral zone the value was 2.66±1.57 (p<0.005). Four of 5 patients who were available for follow-up were detected to have prostate cancer on repeat biopsy. No significant change in metabolite ratio and PSA was observed while ADC showed further reduction on follow-up. CONCLUSION: HGPIN foci have ADC and metabolite ratio values similar to adenocarcinoma prostate, indicating that such patients have a high likelihood of developing cancer. DWI may help identify such men who may be candidates for close follow-up.

The amount of data that is being generated in health care is enormous, especially with the widespread availability of multimedia devices. However, the data keeping in developing countries is still unstructured. Lots of this Big Data is therefore vulnerable to loss. In the current report we highlight the problem and suggest the need for cost effective solution.
