RESUMO

BACKGROUND: The studies have shown that GS given after assessment of the entire prostate gland on the radical prostatectomy specimen may differ from GS given after examination of a small sample from needle core biopsy. We conducted this study to assess discrepancies in the Gleason score between NCB and RP specimens and to find out the correlation between the clinical stage and pathological stage. METHODS: The study included 174 patients with carcinoma prostate which underwent robotic-assisted radical prostatectomy (RARP). Pre-operative Gleason score was determined on 12-core biopsy samples under trans-rectal ultrasound (TRUS) guidance. The Gleason score obtained from the radical prostatectomy specimen was compared with that of the NCB Gleason score to find out differences. RESULTS: The preoperative Gleason score (GS) ranges from 6 to 9 with a mean GS of 6.97 ± 1.02. The post-operative GS ranges between 6 and 10 with mean and GS of 7.5 ± 1.10. On the pre-operative assessment of biopsy specimens, 70 (43.2%) patients had a GS of 6, while 44 patients had a GS of 7 (27.1%) and 48 (29.8%) patients had a GS of more than 7. On the postoperative assessment of specimens, 31 (19.1%) patients had post-operative GS of 6, while 66 (41%) patients had GS of 7 and 74 (41.1%) patients had GS of more than 7. When pre-operative GS and post-operative GS were compared, no changes were observed in the GS of 79 patients, whereas 83 patients showed the difference in GS, with 75 patients showing up-gradation and eight patients marked as down-graded. CONCLUSION: concordance between biopsy and the pathology results directly affects the prognosis of the patient. The results of our study demonstrated the rate of discordance between Gleason scores obtained from transrectal prostate biopsy and RP surgical specimens. This rate brings into question the accuracy of the chosen treatment.

RESUMO

Introduction: Urothelial carcinomas of the bladder are more common in males, making them the sixth-most common cancer in men and the tenth-most common cancer overall, worldwide. Current guidelines do not recommend routine testing for human epidermal growth factor receptor (HER2/neu) expression on the biopsy specimens of patients with urothelial carcinoma. This study was aimed at determining the expression pattern of HER2/neu and its usefulness in muscle-invasive and nonmuscle-invasive urothelial carcinoma. Methods: HER2/neu expression was assessed in 89 specimens of urothelial cancer by immunohistochemistry (IHC), and equivocal cases were subjected to fluorescent in situ hybridization (FISH). Results: On IHC for HER2/neu, 17.9% (7/39) of the muscle-invasive bladder cancers (MIBCs) showed a 3+ expression, whereas 22% (11/50) of the non-muscle invasive cancers were positive with a score of 3+. A significant correlation between HER2/neu status and muscle invasion could not be established in the current study (P = 0.74, Fisher's exact test). Three cases of muscle-invasive (7.7%) and 2 cases (4%) among nonmuscle invasive cancers showed equivocal expression. All the cases with equivocal (2+) expression on IHC were subjected to FISH and none showed gene amplification on hybridization and were considered as negative. Conclusion: Overexpression of HER-2/neu was seen in 17.9% of MIBCs and 22% of non-MIBCs. There are no norms for routine testing of HER2/neu expression in the biopsy specimens of urothelial carcinoma. There is an unmet need to establish guidelines for HER2/neu scoring, similar to that for breast and gastric cancers, to determine the proportion of positive cases and help in identification of those who may benefit from targeted therapies.

RESUMO

INTRODUCTION: We present our initial experience with robot-assisted reconstructive surgeries with the Da Vinci Xi robotic system for benign ureteric pathologies. MATERIALS AND METHODS: This is a retrospective review of prospectively collected data of patients who underwent robot-assisted reconstructive procedures for benign diseases of the ureter at our department from April 2018 to November 2022. Demographic and perioperative details were recorded. Patients were followed up and surgical success was evaluated on the basis of symptomatic, functional, and radiological improvement. RESULTS: A total of 34 patients underwent robot-assisted reconstructions for benign ureteric pathologies by various techniques. Mean age, body mass index (BMI), hospital stay and follow-up duration were 36 years, 24.1 kg/m2, 5.29 days, and 7.08 months respectively. Procedures included pyeloplasty in eight, primary ureteroneocystostomy (UNC) in seven, Psoas hitch UNC in five, Boari flap UNC in six, Ureteroureterostomy in four, ureterocalicostomy in two and ileal ureteral transposition in two patients. Mean docking time, total operative time, and estimated blood loss were 31.5 min, 178 min, and 64.3 ml, respectively. All patients had radiologic or functional improvement on follow-up after 6 months. CONCLUSION: Robot-assisted reconstructive surgery for benign ureteric and bladder pathologies imparted excellent short-term outcomes without major complications with all the advantages of a minimally invasive approach.

RESUMO

INTRODUCTION: Robot-assisted partial nephrectomy (RAPN) can be performed either by a transperitoneal (TP) or a retroperitoneal (RP) approach. However, the superiority of one approach over the other is not established. Hence, the primary aim of this review was to compare perioperative outcomes between these two surgical approaches. METHODS: Literature was systematically searched to identify studies reporting perioperative outcomes following TP RAPN and RP RAPN. The study protocol was registered with PROSPERO (CRD42023399496). The primary outcome was comparing complication rates between the two approaches. RESULTS: This review included 22 studies, 5675 patients, 2524 in the RP group, and 3151 in the TP group. The overall complications were significantly lower in the RP group [Odds ratio (OR) 0.80 (0.67, 0.95), p = 0.01]. However, the rate of major complications was similar between the two groups. The operative time was significantly shorter with the RP group [Mean Difference (MD)-16.7 (- 22.3, - 11.0), p = < 0.0001]. Estimated blood loss (EBL) and need for blood transfusion (BT) were significantly lower in the RP group. There was no difference between the two groups for conversion to radical nephrectomy [OR 0.66 (0.33, 1.33), p = 0.25] or open surgery [OR 0.68 (0.24, 1.92, p = 0.47] and positive surgical margins [OR 0.93 (0.66, 1.31, p = 0.69]. Length of stay (LOS) was shorter in the RP group [MD - 0.27 (- 0.45, - 0.08), p = < 0.00001]. CONCLUSIONS: RP approach, compared to TP, has significantly lower complication rates, EBL, need for BT and LOS. However, due to the lack of randomized studies on the topic, further data is required.

RESUMO

Radical cystectomy with pelvic lymph node dissection is the recommended treatment for managing muscle-invasive carcinoma of the urinary bladder. Early recurrence is observed in only about 4.1% of cases. Port-site metastasis following robot-assisted radical cystectomy is extremely rare. We encountered a challenging and a rare case of bladder cancer that manifested with port-site and peritoneal metastasis within 6 weeks of surgery.

RESUMO

INTRODUCTION: Bladder cancer is a common and serious disease globally, often requiring radical cystectomy as the preferred treatment. However, this procedure carries substantial risks and complications. To evaluate its success, pentafecta, a five-component measure, was introduced. This study investigates the attainment of pentafecta following radical cystectomy and examines factors that influence its achievement. METHODOLOGY: This retrospective, single-group study was conducted at AIIMS Jodhpur. The study population included 42 patients who underwent radical cystectomy for bladder cancer. Various data, including demographic characteristics, clinical features, surgical techniques, and postoperative outcomes, were collected from medical records. The primary outcome measure was the rate of achieving pentafecta, which comprises five parameters. RESULTS: Out of 42 patients, 26 (61.9%) achieved pentafecta. Age, gender, comorbidities and surgical approach did not significantly affect the attainment of pentafecta. Negative surgical margins were achieved in 95.2% of cases, and adequate lymph node dissection (>16 lymph nodes) was performed in 85.7% of cases. The absence of Clavien-Dindo grade 3-5 complications and recurrence was observed in 80.9% and 90.47% of cases, respectively. Uretero-enteric stricture was absent in 95.2% of cases. CONCLUSION: The study emphasizes the significance of negative surgical margins, thorough lymph node dissection, absence of complications, recurrence, and uretero-enteric strictures in evaluating the success of radical cystectomy as pentafacta outcomes. Patients with higher drain output and wound infections are less likely to achieve pentafacta outcome and indicates poorer outcome. By considering these factors, clinicians can assess patient outcomes and identify areas for improvement.

RESUMO

OBJECTIVES: Lymphatic channels (LC) are not as prominent as blood vessels, so they tend to get damaged during surgical procedures. It can present with chyle leak in the postoperative period. We aimed to study the occurrence of chyle leak in patients undergoing nephrectomy and its management. METHODS: During the period of January 2021 and January 2023, 158 adult patients underwent nephrectomy for various reasons like non-functioning kidney, donor nephrectomy, and malignancy. We retrospectively analyzed data of patients who had chyle leak after nephrectomies. RESULTS: Eight patients out of the 158 patients (5.06%) undergoing nephrectomy developed chyle leak. One out of these eight patients underwent nephrectomy by open approach while seven underwent laparoscopic approach. All eight patients who had chyle leak undergone left sided nephrectomy. Six patients of chyle leak could be managed with dietary modification while two patients needed octreotide therapy for treatment. Higher Body Mass Index (BMI; p-value = 0.012), left sides nephrectomy (p-value = 0.013), h/o pyelonephritis (p-value = 0.005) were associated with higher incidence of chyle leak on univariate analysis. While on multivariate analysis no factor was found to be independently associated with chyle leak. Hospital stay was significantly prolonged in patients with chyle leak (p-value = 0.007). CONCLUSION: Chyle leak is not a very rare complication after nephrectomy. Patients with higher BMI, who undergo left sided nephrectomies and patients who had history of pyelonephritis or infectious complications had higher incidence of chyle leak. Most cases can be managed with conservative management (CM). Chyle leak is associated with a prolonged hospital stay.

RESUMO

BACKGROUND: In addition to ensuring cancer control, prevention of incontinence which significantly impact patients' quality of life, is also an important issue in robot-assisted radical prostatectomy (RARP) operations. In this study, we aimed to find the correlation of urinary continence recovery with various factors after Robot assisted radical prostatectomy. METHODS: This study included 162 patients treated with RARP with perioperative data and at least 1 year of follow-up. Also, the preoperative, intraoperative, and postoperative parameters of the patients were analyzed. The continence recovery rate in our study was assessed at 6th week, 3rd month, 6th month, 9th month, and 12th month, post-surgery. Logistic regression analysis evaluated the association between the predictive factors and urinary continence recovery in the early and late stages. RESULTS: The majority of patients with prostate cancer present in sixth decade of life. The majority of our patients (56.7%) were categorized as high risk using D'Amico classification. The continence rate in our study at 6th week, 3rd month, 6th month, 9th month, and 12th month were 40.1%, 72.2%, 85.2%, 89.5%, and 91.4%, respectively. No improvement in continence status was observed after 1 year in our study. There was significant correlation of age with continence status at 6th week, 3rd month, and 6th month. The young age is associated with early recovery of continence. At 3 and 9 months, the non-diabetics cases achieved significantly higher continence rates than diabetics (p < 0.05) which shows that diabetes causes delay in attainment of continence. CONCLUSION: The young age may be associated with early recovery of continence, but further validation requires large number of cases. We attributed good continence recovery rate to meticulous dissection and preservation of good urethral length.

RESUMO

The incidence of urethral recurrence after radical cystectomy is 1% to 8%, with most cases occurring within the first 2 years of surgery. Prophylactic urethrectomy is rarely performed nowadays due to no known survival benefit and increased morbidity due to the procedure. However, we encountered a rare case of delayed urethral recurrence presenting as recurrent urethral collection 4 years after radical cystectomy with ileal conduit diversion, posing a diagnostic dilemma.

RESUMO

During this era of advanced and minimally invasive procedures for treating urolithiasis, percutaneous nephrolithotomy (PCNL) remains the primary choice for removing large renal calculi. While there are various known complications associated with PCNL, such as bleeding, sepsis and injury to neighboring organs, the occurrence of retained foreign bodies as a result of the procedure is rarely reported. In this case report, we present a unique instance of encrustation involving a retained guidewire sheath following PCNL, which was initially mistaken for a residual stone fragment in imaging studies. Fortunately, the foreign body was successfully removed using retrograde intrarenal surgery.

RESUMO

Background and Study Design: Role of 18F-fluoro-2-deoxy-2-d-glucose positron emission tomography-computed tomography (FDG PET-CT) in evaluation of renal cell cancers (RCC) and urinary bladder cancers is not standardized, and the COPPER-T trial, which is a single centre prospective randomized study, was designed to compare it with conventional imaging for staging of clinically localized high risk RCC and urinary bladder carcinoma (Stage T2 and above). Patients and Methods: There will be two subgroups of patients: RCC and urinary bladder carcinoma. In each of these, the patients will be randomized to either Arm A or Arm B. In each of the arms, each patient will be subjected to diagnostic imaging by FDG PET-CT. The CT scan will be a contrast-enhanced scan like that in conventional staging. A radiologist and nuclear medicine specialist will report the scan independently. The radiologist will not have access to the PET scan sequences and will only review the contrast-enhanced computed tomography (CECT) images. In Arm A, the report of the conventional imaging modality, that is, CECT and bone scan if done, will be reviewed first by the clinician, and based on this report, a management plan will be made. Then, the PET-CT report will be reviewed, and change in the management plan will be noted. New findings or equivocal findings if any in the PET-CT report would be noted. In Arm B, the report of the PET-CT report will be reviewed first by the clinicians, and a management plan will be made. Then, the CECT and/or bone scan reports will be reviewed, and any change in the management plan will be noted. Outcome and Significance: Final analysis of the data after completion of the trial will help in clarifying the role of FDG PET-CT in high risk RCC and transitional cell carcinoma (TCC) of the bladder, its diagnostic accuracy compared with conventional imaging and the impact of using it on patient management.

RESUMO

INTRODUCTION: The molecular mapping of cancers by the Cancer Genome Atlas Project has accelerated the quest for new therapeutic targets for urinary bladder cancer, including sex steroid receptors. Previous studies have demonstrated conflicting results on their relationship with bladder cancer, and there is sparse data on their expression in the Indian population. The aim of our study is to examine the expression of androgen receptors (AR) and estrogen receptors (ERα and ERß) in patients with bladder cancer and their correlation with clinicopathologic features. MATERIALS AND METHODS: In this retrospective cohort study, a total of 132 patients, who were surgically managed for urinary bladder mass by transurethral resection or radical cystectomy in our institute, with transitional cell carcinoma on histopathology and with at least two years of follow-up were included. Their demographic and treatment details were obtained, histopathology blocks were retrieved and immunohistochemical staining for androgen and estrogen receptors was performed. Then, the relationship between their expression and clinicopathologic features was studied. RESULTS: A total of 3.79% of patients showed estrogen receptor alpha positivity, 51.52% estrogen receptor beta positivity and 63.64% androgen receptor positivity. No statistically significant correlation was found between age of patients (p = 0.75/0.52/0.87), tumour stage and grade (0.71/0.3/0.21), pathological variant (p = 1/0.58/0.38) and overall survival (p = 0.70/0.052/0.45 for NMIBC and p = 0.82/0.36/0.22) and estrogen receptor alpha, estrogen receptor beta and androgen receptor-positive status, respectively. Estrogen receptor beta positivity was significantly higher in patients with unifocal (p = 0.015) and small tumours (< 5 cm) (p = 0.03), and its expression was associated with better disease-free survival (DFS) (p = 0.046) in patients of non-muscle invasive bladder cancer (NMIBC). CONCLUSION: Our study has the largest sample size conducted on Indian population with results differing from previous studies conducted on western population. Estrogen receptor beta expression was significantly associated with small unifocal tumours and better DFS. Estrogen receptor alpha and androgen receptor expression were not found to be associated with the clinicopathologic features of the study population.

RESUMO

A man in his 50s presented with right flank pain and intermittent haematuria for 15 days. He was evaluated and diagnosed to have bilateral staghorn renal calculi with left poorly functioning kidney. He underwent right kidney stone clearance followed by laparoscopic left simple nephrectomy. Postoperatively, he developed recurrent urinary tract infections. On evaluation, non-contrast CT of the abdomen revealed calculus in left ureteral stump and he was diagnosed to have ureteric stump syndrome. He underwent ureteroscopy which revealed multiple stump calculi and complete stone clearance was achieved. Currently, the patient is asymptomatic and doing well after a follow-up of 1 year.

RESUMO

BACKGROUND: MicroRNAs are small, non-coding RNA molecules that regulate important cellular processes such as tumorigenesis, cell proliferation, and apoptosis. Cancer stem cells are a subset of cells that control metastasis and cell proliferation. In this study, we focus on the roles of miR-10b, miR-21 and correlate with cancer stem cells through the apoptotic pathway in different stages of prostate cancer (PCa). METHODS: In total, 45 patients, each group with Benign prostatic hyperplasia (BPH), localised PCa, and metastatic PCa, were recruited. MicroRNA and gene expression were estimated through quantitative polymerase chain reaction. Flow cytometry was used to characterise prostate cancer stem cells (PCSCs), estimate reactive oxygen species (ROS), apoptosis and chemiluminescent immunoassay was used to estimate interleukin 6 (IL-6), tumour necrosis factor (TNF-α), prostate-specific antigen (PSA), and testosterone. RESULTS: The fold change mean expressions of miR-21, miR-10b, Cytochrome C, and B-cell lymphoma 2 (BCL-2) were significantly upregulated in localised and metastatic PCa compared with BPH. In contrast, the mean fold change expressions of Bcl-2-associated X protein (BAX), Caspase-3, Caspase-9, and Second mitochondria-derived activator of caspase (SMAC) were lower in localised and metastatic PCa compared to BPH. The levels of IL-6, TNF-α, ROS, PSA and testosterone also showed a significant increase while apoptosis was decreased in both localized PCa and metastatic PCa as compared with BPH. In bioinformatics analyses, we found a similar pattern of miRNAs and gene expression in PCa databases. Our study also found a high expression of CD44+/CD24- and CD44+/CD133+ in localised and metastatic PCa compared with BPH. CONCLUSION: Our findings suggest miR-10b and miR-21 promote PCSCs and may target apoptotic genes involved in PCa pathogenesis; these miRNAs could be used as diagnosis biomarkers of PCa. In PCa pathogenesis and PCSCs regulation, the interaction between these two players is crucial and will help develop new PCa therapeutic targets.

RESUMO

Active surveillance (AS), radical prostatectomy (RP), and radical radiotherapy (RT) are the three options for localized prostate cancer. Only a few studies have been conducted in developing countries or in centers in their initial learning curve that predict the outcomes of RARP. Therefore, this study aimed to present data from a novice center; how we started and progressed, and to compare our results with the rest of the world. This is a retrospective analysis to study the outcomes following robot-assisted radical prostatectomy and to identify the predictors of quadrifecta outcomes, i.e., the patients who were continent, did not have complications, were biochemical recurrence free with at least 1 year of follow-up and had negative surgical margins. In our data, we excluded the erectile function as one of the parameters as the majority of our patients were not sexually active or did not want to discuss this parameter. Seventy-two patients were included in this study, and 50 (69.4%) of these achieved the quadrifecta outcomes. Of all the factors, studied, seven factors were statistically significantly different between Group I (quadrifecta achieved) and Group II (quadrifecta not achieved), namely, BMI, co-morbidities like CAD, COPD, ASA grade, pre-op D'Amico risk stratification groups, clinical staging, positive lymph-node status, and hospital stay. With this study, we reported outcomes of RARP in a newly established robotic center and the results were fairly comparable with the well-developed center in India and abroad, emphasizing the short learning curve, and so, the requirement of establishing more robotic surgery centers in developing as well as developed countries.

RESUMO

The development of standardized reporting systems is of paramount importance in medical-imaging. Based on the "RADS" methodology, PIRADS and BI-RADS have been successfully used. The management of bladder cancer (BC) depends on the stage at the time of identification. Accurate assessment of the muscle-invasive stage can alter therapies that are radically different. MRI can accurately diagnose this in a standardized manner (Vesical Imaging-Reporting and Data System: VIRADS) and spare additional procedures. The aim of the study is to determine diagnostic accuracy of VIRADS scoring in evaluation of muscle invasiveness in patients with BC. This study was conducted in a single center over a period of 2 years from April 2020. A total of 76 patients with bladder SOL/diagnosed BC were included. Final VIRADS scoring was calculated and compared with histopathological report.76 patients were evaluated which included 64 males and 12 females. Most of the cases came under the VIRADS-II category (23, 30.26%) followed by VIRADS-V (17, 22.36%). VIRADS-I was reported in 14 cases (18.42%). A total of 8 cases (10.52 %) were reported as VIRADS III and 14 cases (18.42%) as VIRADS IV. VIRADS-III was taken as cut off and found to have a sensitivity of 94.44%, a specificity of 87.50%, a positive predictive value of 87.17% and a negative predictive value of 94.59%. Though number of cases are still less to accurately predict test characteristics of VIRADS, our results are consistent with previously done retrospective studies and VIRADS has got good correlation with pathological staging.

RESUMO

A 29-year-old female presented with the history of pain in the abdomen and a palpable lump in the right hypochondrium, lumbar, and the umbilical regions for the past 2 months. On evaluation with contrast-enhanced computed tomography (CECT) and positron emission tomography CT, she was found to have a heterogeneously enhancing mass entirely replacing the mid and the lower pole of the right kidney, the pelvis, and the upper ureter with loss of fat planes with the inferior vena cava, psoas muscle, and the hepatic flexure, along with pericardial deposits and soft tissue lesions at multiple paravertebral regions and the right thigh. Owing to a high suspicion of metastatic renal cell carcinoma (RCC), a right cytoreductive nephrectomy was performed. Histopathology revealed extranodal Rosai-Dorfman disease, which was mimicking a metastatic RCC on imaging. The patient was started on oral steroids to control the distant lesions and to prevent progression of the disease and is doing well at follow up.

Malakoplakia is an uncommon inflammatory disease that can involve many organ systems but is often encountered in the urogenital tract. Kidney allograft malakoplakia is even rarer and can have a diffuse parenchymal or a pseudotumoral presentation. We describe a case of grafi malakoplakia in an adult female, who presented with dull aching pain in the right loin, fever, and vomiting. Ultrasonography of the kidney graft showed a heterogeneous lesion (2.6 cm × 2.9 cm), raising suspicion of primary or metastatic renal tumors. The diagnosis was established after a histopathological examination of the kidney biopsy. This pseudotumoral presentation of malakoplakia can mimic renal cell carcinoma, lymphoma, fungal infections, or tuberculosis. It is essential to perform a biopsy for establishing the diagnosis.

RESUMO

Objectives Urinary tract infection (UTI) is one of the most common diagnoses in patients visiting urology clinics. Rampant use of empiric and inadequate doses of antibiotics leads to an increase in resistance and poses a huge financial burden. We evaluated UTI in relation to antibiotics used, frequency, susceptibility, and resistance pattern of different pathogens at a tertiary care center and made some important observations. Methods Prospectively 729 patients diagnosed with UTI attending a urology outpatient department from July 2018 to January 2020 were managed accordingly. Antibiotics were started on the basis of urine culture and sensitivity (c/s) or empirically and changed according to subsequent urine c/s. Repeat urine c/s was performed after 5 to 7 days of starting therapy and 10 days after completion of therapy. Results Out of 729 subjects, 417 (57.2%) were males and 312 (42.8%) were females. The most common symptom at diagnosis was dysuria 512 (70.2%), whereas 221 (30.3%) patients presented with fever. Escherichia coli was the most common organism isolated, 453 (62.1%). Among 729 patients, 239 took antibiotics without c/s report, whereas in 490 patients antibiotics were prescribed after the report. A total of 431 (59.1%) patients required one antibiotic session for clearance of pathogen, whereas 135 (18.5%) required two sessions, and three sessions were required in 66 (9%) cases. Among 239 patients whose culture came out to be positive, 145 (60.6%) were found to be resistant to the previously given antibiotic and the common pathogens isolated were E. coli (61 [42%]), Pseudomonas (28 [19.3%]), Enterococcus (22 [15.1%]), Klebsiella (14 [9.6%]), and others. Conclusion Unchecked, rampant, and inadequate use of antibiotics leads to complicated UTI with the increasing share of Pseudomonas, Klebsiella , or other dangerous microbes, which are difficult to treat as well as pose threat in the future.
