Clinical study of steroid receptors in nonmuscle invasive bladder cancer: A domain worth revisiting

Introduction

The prognostic significance of steroid receptors in bladder cancer remains controversial. This study was designed to determine the expression status of androgen receptor (AR), estrogen receptors (ERα and Erβ), and its potential role in predicting survival in patients with nonmuscle invasive bladder cancer (NMIBC).

Methods

Sixty patients of NMIBC were screened and 57 (41 males and 16 females) were included in our study. The tissue microarray slides were evaluated by pathologists blinded to the clinical information. Association of distribution of steroid receptors with stage, grade, progression, and recurrence was seen.

Results

The mean age of the population was 60.9 ± 9.3 years. Pathologically, majority of the patients were Ta (Ta: T1 stage 61.4% vs. 38.6%). Nine (15.8%) of the tumors stained positive for AR while one (1.8%) tumor stained positive for ERα and 36 (63.2%) tumors stained for ERβ. A higher proportion of male NMIBC stained positive for AR (19.5% vs. 6.2%, P = 0.420) while ERβ positivity was higher in females (58.5% vs. and 75%,P = 0.247). AR-negative tumors showed higher recurrence (20/48%-42%) as compared to AR-positive tumors (2/9%-22%). ERβ-positive tumors showed higher recurrence (15/36%-42% vs. 7/21%-33%, P = 0.179). Progression-free survival (PFS) was found to be significantly lower for ERβ-negative group (log-rank test P = 0.035).

Conclusion

AR and ERβ positivity is found in NMIBC patients while ERα shows minimal staining in NMIBC patients. Although it did not reach a statistical significance, a higher proportion of AR-negative and ERβ-positive tumors recurred as compared to AR-positive and ERβ-negative patients. PFS was significantly lower in ERβ-negative group. Further exploratory studies on larger sample sizes are required to validate these findings in NMIBC patients.

Accuracy of combined multi-parametric MRI and PSMA PET-CT in diagnosing localized prostate cancer: newer horizons for a biopsy-free pathway

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.

Oligometastatic carcinoma prostate - An overview of the last decade

Introduction

Oligometastatic prostate cancer (OMPC) has gained profound interest lately due to its different tumor biology and our ability to use multimodality therapy for cure or prolonged survival. Selecting the appropriate patient for treatment has become the aim of treating urologists, medical oncologists, and radiation oncologists. Through this review, we try to highlight the management of OMPC in light of recent literature.

Methods

Literature search was performed on Pubmed, Scopus and Embase using keywords "Oligometastatic", " Prostate Cancer" using operators such as "And" & "Or". Relevant articles were screened and all the latest articles on this emerging entity were included in this review.

Results

All trials relevant to oligometastatic prostate cancer defining the role of surgery, radiotherapy and systemic therapy were included and appropriate inferences were drawn. Relevant studies were compiled in tabular form for this article.

Conclusion

The current standard of care of management for OMPC remains systemic therapy on the lines of hormone-sensitive metastatic prostate cancer. The evolving role of surgery, and radiotherapy along with systemic therapy is highlighted in this article.

Predictors of mortality and nephrectomy in emphysematous pyelonephritis: a tertiary care centre study

INTRODUCTION

Emphysematous pyelonephritis (EPN) is a deadly disease due to its associated morbidity and mortality. Attempts have been made to identify predictors of severity, mortality and need for nephrectomy in EPN with little success.

METHODS

We conducted an ambispective study of EPN patients between March 2014 and September 2019. Retrospective data were collected which included age, sex, comorbidities, symptoms, signs, laboratory investigations including imaging, need for dialysis, management and any complications. All patients were then followed prospectively for renal dynamic scan, stone surgery or nephrectomy. Univariate analysis was performed to identify factors affecting mortality and need for elective nephrectomy.

RESULTS

In total, 112 patients were included. Mean patient age was 50.01 years, 55% were female and 5% had bilateral involvement. Fever and flank pain were the most common symptoms. Diabetes was seen in 75% of cases and 30% of cases required haemodialysis at initial presentation. About 60% of patients improved with pigtail drainage. Need for nephrectomy was greater in Huang-Tseng stage 3a (14.8%). Huang-Tseng stages 3b and 4 had higher mortality rates (25%) than the other stages (2.2%). Twelve of 99 patients had non functional kidney on follow-up and underwent elective nephrectomy. Low platelet counts, high body mass index, septic shock, dialysis and higher Huang-Tseng stage were found to be predictive of mortality and renal parenchymal thickness on computed tomography scan was predictive of follow-up nephrectomy.

CONCLUSIONS

Thrombocytopaenia, high body mass index, septic shock, haemodialysis and higher Huang-Tseng stage are predictors of mortality and renal parenchymal thickness <5mm is a predictor of poor salvage of affected kidney on follow-up.

Preoperative Predictors for the Presence of Motile Spermatozoa in the Epididymis and Patency of Anastomosis during Microsurgical Vasoepididymal Anastomosis in Patients with Obstructive Azoospermia

Background

Following microsurgical vaso-epididymal anastomosis (VEA), anastomotic patency with sperm returning to the ejaculate is not always present and may even be delayed. The presence of motile spermatozoa is highly suggestive of future patency following surgery.

Aims

We prospectively analyse the factors that could predict motile spermatozoa at the epididymis intraoperatively and predictors of patency in patients with obstructive azoospermia (OA) undergoing microsurgical VEA.

Settings and Design

Department of Urology of a tertiary care centre in Northern India. It is a prospective observational study.

Materials and Methods

Over a 2-year period (July 2019 to June 2021), 26 patients with idiopathic OA were enrolled in the study. Twenty patients underwent microsurgical VEA. Patients were divided into two groups based on the presence/absence of intraoperative motile spermatozoa.

Statistical Analysis Used

Analysis of preoperative and intraoperative factors was done using the Mann-Whitney U-test, Chi-squared test and Fischer exact test.

Results

Out of 20 patients, 5 (group 2) had intraoperative motile spermatozoa in the epididymal fluid and 15 (group 1) had nonmotile spermatozoa. Low luteinising hormone (LH) levels (P = 0.01) and high testosterone levels (P = 0.05) were the predictive of presence of motile spermatozoa in epididymal fluid. Mean follow-up was 9 months (6-18 months). Predictors of higher patency were grade 2 epididymis (firm, turgid and tense) (P = 0.003), low LH levels (P = 0.03), low sertoli cell index (P = 0.006), high sperm-Sertoli index (P = 0.002) and better surgeon satisfaction (P = 0.01).

Conclusion

Low LH levels and high testosterone levels may be predictive of the presence of motile spermatozoa in epididymal fluid. Firm, turgid and tense epididymis, low Sertoli cell index, high sperm-Sertoli index and surgeon satisfaction suggest a greater chance of success after VEA for idiopathic azoospermia.

Quality of Life, Efficacy, and Safety of Sequential Intravesical Gemcitabine + Docetaxel versus BCG for Non-Muscle Invasive Urinary Bladder Cancer: A Pilot Study

PURPOSE

Bacille Calmette-Guerin (BCG) is considered the most effective agent for non-muscle invasive bladder cancer (NMIBC). However, due to BCG-related toxicity, multiple studies have suggested the role of newer chemotherapeutic drugs. The aim of our study was to evaluate intravesical gemcitabine + docetaxel (Gem/Doce) versus BCG with respect to quality of life (QOL), safety, and efficacy in NMIBC.

METHODS

A total of 60 patients with NMIBC were evaluated between July 2019 and December 2020 in a prospective manner. The sample size calculation was done, keeping in mind the incidence of intravesical BCG-related complications of up to 50-60% and 20-30% for Gem/Doce combination. The p value of 0.05 was kept as statistically significant. The enrollment ratio was kept at 1, and power of study was aimed at 80%. The study population was alternatively assigned to two groups (BCG vs. Gem/Doce) of 30 patients each. Both the groups received 6 weekly doses of induction therapy followed by 6 monthly doses of maintenance therapy if no recurrence was noted at interim follow-up. QOL scores, safety, and efficacy were assessed at beginning of intravesical therapy, end of induction, and 6 months of maintenance therapy. Cystoscopy examination and cytology were performed at the end of induction therapy and 3-monthly thereafter.

RESULT

The preliminary results at the end of 6 months following maintenance therapy showed that the demographic profile, histological stage, and grade were comparable between two groups. The QOL scores using QLQ-30 and QLQ-BLS-24 showed statistically significant differences with the Gem/Doce arm showing better outcomes. There were no progressions to higher stage, while one recurrence each was seen in both groups. Patient-related side effects measured by CTCAE (Common Terminology Criteria for Adverse Events)version 5 showed that the BCG group had higher toxicity profile as compared to Gem/Doce group.

CONCLUSION

Gem/Doce combination intravesical therapy is a promising alternative to BCG for treatment of NMIBC, showing better QOL measures and lesser side effects.

Primary bladder neck obstruction in female: 'an enigmatic disorder'

A 36-year-old woman presented with problems of lower urinary tract symptoms for 2 years duration. Patient was being managed as a case of urethral stricture with routine calibration. Micturating cystourethrogram showed failure of bladder neck to open. On urodynamic study, she was found to have bladder outlet obstruction with high pressure, low flow pattern. Based on these findings, patient was diagnosed to have primary bladder neck obstruction (PBNO). She was also being evaluated for primary infertility and was to undergo in vitro fertilisation. She successfully underwent bladder neck incision after discussion about management options. Bladder neck incision is one of the accepted management options for PBNO. Post procedure patient was relieved of symptoms and also had an uneventful full-term pregnancy. Bladder neck incision in women is an effective treatment option when patient has been properly selected and procedure done with expert hands.

Evaluation of YouTube Videos as a Source of Patient Information for Ureteric Stent Placement: A Quality Assessment Study

Objective

To assess the quality of YouTube videos on ureteric stent placement (USP) as a source of patient available.

Methods

YouTube was searched using search terms “DJ stenting,” “Double J stenting,” and “ureteric stenting.” The initial 100 videos displayed with each of the above mentioned search terms were scrutinized. The selected videos reviewed by 3 independent consultant urologists against a pre-agreed scoring system based upon European Association of Urology (EAU) patient information sheet on ureteric stent placement. The videos were scored qualitatively and quantitatively based on the scores achieved in various domains of the scoring Performa. Data was also collected for the number of views, likes, dislikes, and time duration of each video.

Results

A total of 22 videos which fulfilled the inclusion criteria were reviewed. All the videos were uploaded by healthcare organizations or healthcare websites. None of the videos were classified as “Good” based on reviewer scores and only one video was classified as “acceptable.” Fourteen videos were classified as “very poor” with a score of <5/20. General information about stents was described by majority of the studies whilst preoperative information, procedure description, danger signs, and follow up were scarcely described by most videos.

Conclusion

Majority of YouTube videos on USP are of poor overall quality and lack pertinent information. This calls for creation of comprehensive and unbiased videos for patient information on USP.

Utility of WhatsApp in emergency urological practice: An interrater reliability study

INTRODUCTION

The messaging application 'WhatsApp' is used in clinical practice, often for communication between a medical trainee and a consultant. We designed this study to find the interrater reliability of the data transmitted through this application and validating its use in urological practice.

MATERIALS AND METHODS

Clinical details and computerized tomographic (CT) images of 30 patients visiting the urology emergency were posted in a closed WhatsApp group involving three consultants (SKD, APS, and KC). The CT images were posted in the WhatsApp group as Whole Image (WI) and Image of Interest (IOI) format and rated on a scale of 1-5. The consultants formulated a provisional diagnosis and initial management strategy. The interrater reliability of these responses was analyzed in the study.

RESULTS

Mean WI rating ranged from 3.03 ± 0.61 to 3.73 ± 0.64 (Cronbach alfa [α]-0.494, P = 0.006). Mean IOI rating ranged from 3.4 ± 0.56 to 4.13 ± 0.73 (α-0.824, P < 0.0001). For diagnosis, the proportion of observed agreement (P₀) was 83.3% for SKD and APS, 76.6% for SKD and KC, and 73.3% for APS and KC. For management, P₀ was 86.6% for APS and KC, 86.6% for SKD and APS, and 80% for SKD and KC.

CONCLUSIONS

WhatsApp Messenger serves to transmit good quality pictures of CT scan images. A reasonable diagnosis and management strategy can be formulated using this app with fair inter-rater reliability.

Iatrogenic partial glanular amputation: A rare complication of circumcision

Circumcision is a customary ritual across many cultures. However, the safety of such procedures remains a concern. A boy underwent circumcision in 2014 by a religious worker at the age of 7 years. Post circumcision, the patient had gradual narrowing of the penis, between the glans and the shaft, with an iatrogenic partial glanular amputation and presented to us at the age of 14 years. The patient underwent end-to-end urethroplasty and glansplasty. Postoperatively, the patient did well and the wound remained healthy. Circumcision has complications even in expert hands. Religious circumcision can result in dreadful complications in children and adolescents.

Robot-assisted partial nephrectomy for moderate to highly complex renal masses. A systematic review and meta-analysis

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.

What should urologists know about Pseudojournals and open access publishing? A narrative review of the literature

Introduction

The majority of the open access publishing allows the researchers to publish their articles for a fee and at the same time enables the readers to access the research without paying the expensive journal subscription charges. Under the garb of open access publishing, predatory journals run a scam to dupe the researchers of money. This study was conducted to highlight the characteristics of pseudojournals and increase the awareness about their modus operandi.

Methods

The email inboxes of 3 academic urologists (APS, AS, and KP) were searched for emails soliciting articles for open access journals. A list of all such journals was compiled. These journals were checked for metrics from the Journal Citation Reports and the Scimago Journal Rankings. All these journals were then cross-checked with the available whitelists and blacklists. Features pointing toward a pseudo journal were identified as red flag signs for these journals and were noted. A literature search was performed on open access publishing and predatory journals, and the salient points were noted. A checklist of red flag signs was compiled.

Results

A total of 71 emails soliciting article submissions from 68 journals were received by the three urologists (APS, AS, KP). Of these, 54 were highly suggestive of being a pseudojournal, 5 journals were operating in the gray zone between genuine open access journals and outright predatory journals, and 9 were genuine open access journals. A total of 33 articles on predatory journals were reviewed after the literature search as per the PRISMA guidelines. The red flag signs identified along with the literature review were used to create the SAFEiMAP checklist, which can be used to identify predatory journals.

Conclusion

Predatory journals have infiltrated the whitelists, and the indexing databases like PubMed and no blacklist is all-inclusive. Understanding the concept and the types of open access publishing gives the researchers a better idea on how to differentiate fake journals from the genuine ones. Using a checklist will help to identify the red flag signs of such journals and identify those journals that operate in the gray zone.

High rising flames: a sign of complex extraperitoneal bladder rupture

Extraperitoneal bladder rupture is the most common type of bladder injury following pelvic trauma and is seen in 80-90% of cases. Generally, the contrast extravasation seen on computed tomography (CT) cystography is confined to the perivesical space, giving a characteristic flame-shaped appearance. Occasionally contrast extravasation can extend to the scrotum, thigh or anterior abdominal wall, depending on the extent of injury. Here we report an unusual CT cystogram finding of complex extraperitoneal bladder rupture with associated pelvic fracture urethral distraction defect, showing large-volume contrast extravasation extending beyond the perivesical space to the left perinephric region resembling high rising flames.

Primary primitive neuroectodermal tumour of the kidney in adults: Experience of managing 12 cases with systematic review and pooled analysis of literature

INTRODUCTION

Primitive neuroectodermal tumor (PNET) of the kidney is unusual in adults. These tumours are diagnosed mainly on histopathology and that too sometimes has limitations. With this study, we aimed to review our clinical and histopathological data of patients with renal PNET and reviewing the world literature.

METHODS

In this retrospective study, we reviewed our database from January 2006 to July 2018 to include all the cases of primary PNET of the kidney. We also performed systematic literature search to identify all the relevant series on renal PNET.

RESULTS

A total of 12 patients including 5 men and 7 women were managed during the above mentioned period. Out of these 7 patients, 2 patients had metastasis at diagnosis, one had locally advanced disease, 6 underwent radical nephrectomy, 5 patients received adjuvant chemotherapy (two currently receiving) and only 1 patient received adjuvant radiotherapy (RT). On Immunohistochemistry (IHC), CD99 and FLI1 were positive in all the patients. Median survival was 10 months. In our review 10 studies were included, 38.6% of the patients had metastatic disease and 10.7% had locally advanced disease at diagnosis. Overall mean survival was 33.75 months. CD99 and FLI1 were positive in 94.3% and 78.5%, respectively.

CONCLUSION

PNET remains a pathological diagnosis and IHC has important place in diagnosis of PNET. Locally advanced and metastatic disease is common at diagnosis leading to overall poor survival.

Trifecta and pentafecta outcomes following robot-assisted partial nephrectomy for hilar versus nonhilar tumors: A propensity-matched analysis

Introduction

Hilar tumors are a unique subset of complex renal masses posing a potential surgical challenge during partial nephrectomy. The outcomes of hilar masses have not been compared to non-hilar renal masses of similar RENAL nephrometry score (RNS). In this study, we analyzed the outcomes of hilar versus nonhilar masses after a propensity score matching.

Methods

Prospectively maintained database of patients who underwent robot assisted PN between November 2014 and December 2018 was abstracted for hilar and nonhilar tumors. We performed propensity matching for baseline variables such as age, sex, body mass index, comorbidities, preoperative glomerular filtration rate, and RNS for each patient on the basis of propensity scores.

Results

We included 48 patients with hilar tumors and 153 with nonhilar tumors. On propensity matching, 41 patients were included in each group. The mean operative time (162.4 ± 48.9 min vs. 144.1 ± 38.8 min, P = 0.48), warm ischemia time (29.0 ± 8.8 min vs. 24.4 ± 8.2 min, P = 0.12), and the estimated blood loss (201.8 ± 184.7 ml vs. 150.6 ± 160.5 ml, P = 0.37) were not significantly different between the hilar and the nonhilar groups. Trifecta was achieved in only 14/41 (34.1%) of the patients in the hilar group as compared to 24/41 (58.5%) in the nonhilar group (P = 0.027). Logistic regression analysis identified that hilar location of the tumors was not an independent predictor of overall complications (OR 6.37, confidence interval [CI] 0.5-69.4, P = 0.4), trifecta (OR 0.38, CI 0.14-1.0, P = 0.051), and pentafecta outcomes (OR 0.4, CI 0.1-1.51, P = 0.17).

Conclusions

Hilar location was associated with poorer trifecta outcomes compared to the nonhilar tumors. However, hilar location per se was not an independent predictor of overall complications and trifecta and pentafecta outcomes.

Skin nodules and proptosis in a case of carcinoma urinary bladder: An unusual presentation

Metastasis to the skin and orbit from bladder cancer is extremely rare. A 76-year-old diabetic male presented with skin nodules and proptosis of the left eye. Punch biopsy from the abdominal wall nodule showed malignant cells with perineural invasion. Immunohistochemistry showed features suggestive of metastatic urothelial carcinoma. We present this case of urothelial carcinoma of the urinary bladder presenting primarily with highly unusual nodular skin metastasis.

Safety and efficacy of "on-demand" tramadol in patients with premature ejaculation: an updated meta-analysis

INTRODUCTION

Tramadol has been used for the treatment of premature ejaculation, however, the studies published for the same are not well designed. The primary objective of this study was to explore the literature pertaining to the use of tramadol in patients with PE to determine its safety and efficacy in this population. Materials ande methods: Systematic literature search of various electronic databases was conducted to include all the randomized studies and quasi-randomized studies. Standard PRISMA (Preferred reporting Items for Systematic reviews and Meta-analysis) guidelines were pursued for this review and study protocol was registered with PROSPERO (CRD42019123381).

RESULTS

Out of 9 studies included in this review, 5 were randomized controlled trials, and rests of the 4 studies were quasi-randomized studies. Tramadol resulted in significantly higher improvement of IELT with the mean difference (MD) of 139.6 seconds and confidence interval (CI) 106.5-172.6 seconds with a p-value of p < 0.00001. All dosages except 25mg fared well as compared to placebo. Tramadol fared better than placebo at 1 month, 2 months, and 3 months after initiation of therapy as compared to the placebo. Tramadol group had reported a significantly higher number of adverse events with treatment as compared to placebo but none of them were serious.

CONCLUSION

Tramadol appears to be an effective drug for the management of PE with a low propensity for serious adverse events. However, evidence obtained from this study is of low to moderate quality. Furthermore, effective dose and duration of therapy remain elusive.

Paradigm Shift in Clinical Practice of Sexual Health in Men During COVID-19 Pandemic

Sexual health-care seeking behavior and practices have been affected during COVID-19 pandemic. The impact of COVID-19 on this subspecialty is far reaching. This study aimed to assess the impact of COVID-19 on health-care seeking practice pertaining to sexual health in men in our tertiary care center and review the relevant literature regarding impact of COVID-19 on sexual health seeking practice and challenges faced. Outpatient data was analyzed from January 2019 to April 2021. Patients awaiting surgical procedures due to COVID were documented. A narrative synthesis of literature based on systematic search using the keywords sexual health, sexual health seeking, sexual health practice, andrology, and COVID with operators “AND” and “OR” was carried out in three search engines PubMed, Scopus, and Embase. The study outcomes were obtained by comparing data of outpatient attendance and compiling the reviewed literature. The mean attendance fell significantly from 95.11±11.17 to 17.25±13.70 persons (P <.0001) per outpatient clinic, March 2020 being the reference point. Teleconsultation has taken over physical consultation. In 98/949 cases, teleconsult could not be provided despite registration. Over 25 patients were waiting for surgical procedures pertaining to andrology due to shut down of elective services. Similar trends have been reported from other countries. Number of patients seeking consultation for sexual health problems has dramatically decreased during COVID-19 era. Establishment of data safe teleconsultation facility and its widespread advertisement is needed to encourage patients to seek consult.

The Adequacy of Pelvic Lymphadenectomy During Radical Cystectomy for Carcinoma Urinary Bladder: A Narrative Review of Literature

An adequate pelvic lymph node dissection (PLND) is an essential part of radical cystectomy for muscle invasive bladder cancer. However, the definition of what constitutes an adequate PLND is often shrouded in controversy. Various authors have defined different anatomic templates of PLND based on levels of pelvic lymph nodes. Some have suggested other surrogate markers of the adequacy of PLND, namely lymph node count and lymph node density. While individual studies have shown the efficacy and reliability of some of the above markers, none of them have been recommended forthright due to the absence of robust prospective data. The use of non-standardized nomenclature while referring to the above variables has made this matter more complex. Most of older data seems to favor use of extended template of PLND over the standard template. On the other hand, one recent randomized controlled trial (RCT) did not show any benefit of one template over the other in terms of survival benefit, but the study design allowed for a large margin of bias. Therefore, we conducted a systematic search of literature using EMBASE, Medline, and PubMed using PRISMA-P checklist for articles in English Language published over last 20 years. Out of 132 relevant articles, 47 articles were included in the final review. We have reviewed existing literature and guidelines and have attempted to provide a few suggestions toward a uniform nomenclature for the various anatomical descriptions and the extent of PLND done while doing a radical cystectomy. The results of another large RCT (SWOG S1011) are awaited and until we have a definitive evidence, we should adhere to these suggestions as much as possible and deal with each patient on a case to case basis.

Absence of SARS-CoV-2 infection in the semen of men recovering from COVID-19 infection: An exploratory study and review of literature

The effect of COVID-19 on the male reproductive tract has been sparsely studied. This exploratory study was designed to determine the presence of SARS-CoV-2 in the semen of men recovering from COVID-19. A systematic literature review was also performed as per PRISMA guidelines to gather perspective on this topic. The prospective study included men 21 years and older recovering from COVID-19 with nasopharyngeal swab negative for SARS-CoV-2 or at least two weeks from the last COVID RT-PCR positivity. After clinical evaluation, freshly ejaculated semen sample by masturbation was collected in a sterile container. Samples were processed for the detection of SARS-CoV-2 by RT-PCR. Twenty-one patients were contacted for the study, 11 of which consented to provide a semen sample. The mean age of the cohort was 29.72 ± 4.52 years. None of the patients gave a history of epididymo-orchitis or sexual dysfunction at the time of assessment. None of the semen samples demonstrated SARS-CoV-2 on RT-PCR. Median duration of semen sample collection from the COVID positivity was 44 days (Range 19-59 days). Detailed literature review revealed that SARS-CoV-2 is not found in patients recovering from COVID-19 infection. We conclude that SARS-CoV-2 is not found in the semen of patients recovering from COVID-19.

Atrophic Kidney-Like Lesion - Case Report of A Provisional Entity with Brief Review of Literature

Atrophic kidney-like lesion is a recently recognized entity, post 2016 World Health Organization Classification of tumors of the urinary system. The behavior of this tumor is not fully known as only a handful of cases with limited follow-up are available. This entity closely mimics thyroid-like follicular carcinoma of the kidney, which has different prognosis. We report a case of incidentally detected atrophic kidney-like lesion in an elderly gentleman who had urothelial carcinoma of the urinary bladder with a brief review of literature. Atrophic kidney-like lesion and urothelial carcinoma of the urinary bladder association has not been reported in the literature.

Effect of Transurethral Resection of the Prostate on Urodynamic Parameters in Patients with Benign Prostatic Enlargement with Upper Urinary Tract Dilatation

OBJECTIVE

To evaluate the urodynamic outcomes of transurethral resection of the prostate (TURP) in patients of benign prostatic enlargement (BPE) with upper urinary tract dilatation and correlate with International Prostate Symptoms Score (I-PSS).

METHODS

In this prospective study, patients of BPE with upper urinary tract dilatation from July 2017 to June 2019 were enrolled. At presentation, detailed I-PSS, ultrasonography abdomen, serum creatinine, and serum PSA were recorded. All the patients were catheterized and observed for postobstructive diuresis. At 4 weeks, repeat ultrasound and serum creatinine were recorded. Urodynamic study (UDS) was performed after ensuring sterile urine culture. Patients underwent TURP as per the standard technique. A repeat UDS was performed after 3 months, and analysis was done.

RESULTS

Forty-four patients were enrolled of which data of 37 patients were analyzed. In the filling phase of the UDS, there was a significant decrease in detrusor pressure at the end filling phase from 27 to 9.0 cm H2O after TURP. Maximum cystometric capacity and bladder compliance significantly improved at 3 months following surgery. In the voiding phase, peak flow rate showed a significant increase, postvoid residual urine volume significantly decreased, and peak detrusor pressure marginally decreased following TURP. The I-PSS decreased from 20 ± 8 to 5 ± 6 following TURP.

CONCLUSION

High detrusor pressure and reduced compliance is a risk factor for upper urinary tract dilatation. Changes in the bladder dynamics and resolution of hydronephrosis following TURP reflected in the changes in urodynamic parameters and I-PSS.

A huge ureteric stone in a functionally, metabolically and anatomically normal kidney: an alliance of rarity

Urinary stones are a common health problem, necessitating frequent outpatient visits and hospital admissions. Ureteric stones demand special attention, given their propensity for upstream hydroureteronephrosis and loss of renal function. They are usually predisposed by diverse anatomical, functional or metabolic abnormalities of the urinary tract and have an early symptomatic presentation. We report an exceptional clinical presentation of a huge ureteric stone yet functional renal moiety with no obvious anatomical or metabolic predilection for urolithiasis, and its minimally invasive management in a young woman. We emphasise that swift salvaging of the renal function is of utmost importance in these cases. Open exploration can be avoided in favour of laparoscopic ureterolithotomy with better cosmesis and early recovery.

Comparison of efficacy of three commonly used alpha-blockers as medical expulsive therapy for distal ureter stones: A systematic review and network meta-analysis

Introduction:

The efficacy of alpha-blockers as medical expulsive therapy (MET) is well established. However, it is not known which of the three most commonly used alpha-blockers (tamsulosin, alfuzosin and silodosin) is the most efficacious. With this study we aimed to assess the efficacy of the three commonly used alpha-blockers as MET for distal ureter stones.

Materials and Methods:

For this review, we searched multiple databases such as PubMed/Medline, Scopus, Embase, OviD SP, CINAHL, and web of science to identify all the relevant randomized studies comparing the efficacy of tamsulosin, alfuzosin, and silodosin. Preferred reporting items for systematic reviews for network meta-analysis (PRISMA-NMA) were followed while conducting this review and the study protocol was registered with PROSPERO (CRD42020175706).

Results:

In this review, 31 studies with 7077 patients were included. Compared to placebo all the treatment groups were more effective for both stone expulsion rate (SER) and stone expulsion time (SET). For both SER and SET, silodosin had the highest SUCRA (94.8 and 90.4) values followed by alfuzosin (58.8 and 64.9) and tamsulosin (46.2 and 44.5). The incidence of postural hypotension was similar with all the drugs, whereas, the incidence of retrograde ejaculation was significantly higher for silodosin. Overall confidence for each comparison group in this review ranged from “very low” to “moderate” according to the CINeMA approach.

Conclusion:

Among the three commonly used alpha-blockers silodosin is the most efficacious drug as MET for lower ureter stones followed by alfuzosin and tamsulosin.

Does Miniaturization Actually Decrease Bleeding After Percutaneous Nephrolithotomy? A Single-Center Randomized Trial

Introduction: Miniaturization of percutaneous nephrolithotomy (mPCNL) was proposed to decrease postoperative bleeding, as there is decreased parenchymal injury compared with standard percutaneous nephrolithotomy (SPCNL). Published randomized controlled trials (RCTs) evaluating bleeding after mPCNL have shown conflicting results. Hence, the evidence to say that mPCNL offers less postoperative bleeding is not robust. Materials and Methods: Prospective RCT was done by comparing mPCNL and SPCNL for treatment of renal stones of size 1 to 3 cm. Patients with active urinary tract infection, renal malformation, uncorrected coagulopathy, and raised serum creatinine (>1.5 mg/dL) were excluded. Blood loss was evaluated by measuring fall in hemoglobin and hematocrit on postoperative day 1. Postoperative pain was evaluated by visual analogue scale (VAS) score at 6, 24, and 48 hours. Results: A total of 60 patients (30 in each arm) were enrolled during the study period. All the baseline preoperative variables were comparable in both the groups. The SPCNL group had a significantly higher drop in hematocrit level as compared with mPCNL (4.6 ± 3.1% vs 3.1 ± 2.1%, p = 0.02). The mean fall in hemoglobin was higher in SPCNL as compared with mPCNL (1.61 ± 0.9 gm% vs 1.21 ± 0.7 gm%, p = 0.07), but it was not significant. Blood transfusion (BT) rate was comparable in both the groups (one patient in each group). The mPCNL group had significantly less VAS scores at 6 hours (3.27 ± 1.20 vs 4.40 ± 1.52, p = 0.002) and 24 hours (2.10 ± 0.54 vs 2.83 ± 1.05, p = 0.001) after surgery. Postoperative complications and hospital stay were comparable in both the arms. Conclusion: mPCNL is associated with less postoperative bleeding and pain than SPCNL. However, the small tract size does not prevent against the clinically significant bleeding requiring BT.

Teleconsultation for paraphimosis reduction in the geriatric population: Lessons from the COVID-19 pandemic

The health-care sector has been drastically overwhelmed in the wake of prevailing COVID-19 pandemic, hampering elective and emergency medical services alike. The geriatric population is especially affected in this regard as they are the ones who need access to health care services the most, and unfortunately, they are the ones with the highest risk of cross infection and mortality with SARS-COV-2. Lockdown and public restrictions have made the accessibility even harder. Telemedicine has emerged as a useful tool that avoids the risk of cross infection during the face-to-face consultation. Numerous guidelines have been made regarding the implementation of teleconsultations during this pandemic. Through this report, we describe the "beyond guidelines" emergency management of paraphimosis in an aged, bedridden male with comorbidities, through teleconsultation amid the COVID-19 pandemic.

Isolated renal vein and inferior vena cava thrombosis in a young man with ulcerative colitis: diagnostic challenges and lessons learned

We present a case of a young man, known case of ulcerative colitis, who presented with acute onset right flank pain and haematuria. Blood workup showed leucocytosis and raised serum creatinine. Cross-sectional imaging revealed renal vein with inferior vena cava thrombosis. He had a normal infectious screen and lacked septic features pointing towards non-infectious pathology. The 24-hour urine examination revealed nephrotic range proteinuria. Further evaluation was inconclusive for any defined pathology. Empiric anticoagulation was started and patient responded miraculously with restoration of vascularity to the affected kidney and discharged in stable condition.

Gummatous Syphilis: A Rare Entity Mimicking Carcinoma Penis

OBJECTIVE

To describe a rare case of gummatous syphilis of the penis with urethrocutaneous fistula mimicking penile carcinoma causing a diagnostic dilemma.

METHOD

A 54 year old man presented with an ulcerative lesion on glans penis. Patient was managed with partial penectomy in view of erosive growth giving rise to urethrocutaneous fistula.

RESULTS

Histopathology showed granulation tissue, necrotizing vasculitis and epithelioid cell granuloma. Immunohistochemistry stained positive for Treponema and patient was treated accordingly.

CONCLUSION

Syphilis is rarely encountered in daily clinical practice in the penicillin era. Despite a negative serology and the clinical picture highly suggestive of malignancy, the histopathology helped in clinching the rare diagnosis.

Clinical spectrum, diagnosis, and sexual dysfunction after repair of fracture penis: Is no news good news?

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.

Endovascular Embolization of a Previously Treated Renal Arteriovenous Malformation Presenting With Gross Hematuria

Renal arteriovenous shunts are direct communications between the supplying artery and draining vein without the presence of an intervening capillary bed. They can be traumatic or nontraumatic. Coils can be used for embolization of feeding arteries; however, they do not treat the nidus directly. We report a case in which proximal coil placement in feeding arteries led to recanalization of the renal AV shunt through collaterals, resulting in recurrent hematuria. The case was subsequently managed by embolizing the nidus by N-butyl 2-cyanoacrylate glue.

Safety and efficacy of bipolar versus monopolar transurethral resection of bladder tumor: a systematic review and meta-analysis

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.

Arteriovenous malformation with a renal mass: A rare association

Renal arteriovenous malformation can be rarely associated with a renal mass. A vigilant approach and careful planning is required to tackle both the pathologies in form of preoperative coil embolization followed by a minimally invasive radical nephrectomy.

IgG4-related Retroperitoneal Fibrosis: An Emerging Masquerader With a Sinister Presentation

OBJECTIVE

Retroperitoneal fibrosis (RPF) is a rare proliferative fibro-inflammatory disease involving the soft tissues of the retroperitoneum. IgG4 related retroperitoneal fibrosis is an emerging entity which needs to be distinguished from idiopathic RPF. We describe a clinical case of IgG4 related RPF highlighting the importance of clinching this diagnosis.

METHODS

A 70 year old female was referred to the outpatient department of our institute with complaints of fatigue, bilateral flank pain and loss of appetite for the past 1 month. The CT and PET scan demonstrated a uniformly enhancing bulky retroperitoneal mass causing bilateral hydroureteronephrosis. The biopsy from the mass lesion revealed IgG4 related disease. The patient was started on corticosteroids after percutaneous nephrostomy placement.

RESULTS

Three months post induction of therapy, repeat PET-CT shows resolution of the mass with no FDG avid lesion. Serum IgG4 levels were reduced to normal (27 mg/dL) suggestive of response to treatment. The percutaneous nephrostomies were removed and the patient is doing well on maintenance dose of corticosteroids for her disease.

CONCLUSION

The availability of serum IgG4 levels for monitoring treatment response and follow-up can curtail the repeated radiological imaging and associated contrast exposure as compared to idiopathic RPF. Secondly, the diagnosis of IgG4-related RPF shall alert the clinician to look out for extra-retroperitoneal diseases on follow up of this multi-organ disease.

Prominent swelling on erection: Perineal angiomyxoma as a rare entity

Perineal angiomyxoma is a rare entity, more commonly seen in females. We report a case of a 44 year old male who presented with a perineal swelling which became prominent with penile erections. Magnetic Resonance Imaging (MRI) revealed a T1 hypointense and T2 hyperintense midline lesion (4.6 × 2.5 × 5 cm) in relation to corpus spongiosum, with ill defined fat planes with the bulbospongiosus muscle and progressive enhancement on dynamic contrast sequence. A differential diagnosis of soft tissue sarcoma or hemangioma was made and the mass was completely excised via a midline perineal incision. The histopathology revealed features consistent with angiomyxoma.

Exophytic benign prostatic hyperplasia presenting with refractory retention: A rare entity

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.
