PurposeTo study clinical presentation, laboratory results, imaging findings and treatment options and outcomes of retroperitoneal fibrosis (RPF). To determine whether it follows the same natural course and response to treatment in the Asian population as in the Western world.Materials and MethodsMedical records of patients diagnosed with RPF on imaging and histopathology between February 2010 and April 2016 were reviewed.ResultsOf the 21 patients analyzed, mean age at presentation was 50.81 years. The male to female ratio was 0.9:1. Pain was most common presenting complaint (95.23% cases), almost 85% cases were idiopathic and rests were postradiation induced. The median creatinine level was 1.8 mg/dL. The mean erythrocyte sedimentation rate (ESR) was 53.2 mm/h. Hydronephrosis was present in all patients and 47.6% had atrophic kidneys. Diffuse retroperitoneal mass was present in 61.1%. Ureterolysis with lateralization, omental wrapping or gonadal pedicle wrap was done in 17 cases. Two patients underwent uretero-ureterostomy. One patient underwent ileal replacement of ureter, and one ileal conduit. Eighteen patients received concurrent medical treatment, 11 were given tamoxifen, 2 steroids (Prednisolone), and five were given both. Of the 20 patients with follow-up, 70% had complete symptomatic relief; ESR improvement was seen in 77.8%. Follow-up ultrasound showed resolved and decreased hydronephrosis in 20% and 55% respectively. One patient had treatment failure and 17.65% had disease recurrence.ConclusionsRPF is a rare disease with varied presentation and outcomes. The male to female ratio may be equal in Asians and smoking could be lesser contributing factor. More Asian cohort studies are required to support same.
Prostatic utricle cyst is a rare congenital anomaly. Symptomatic cysts require treatment. Surgical excision is the treatment of choice, but is challenging due to close proximity to vas deferens, ejaculatory ducts, bladder, prostate, rectum and pelvic nerves. Complications include rectal injury, ureteral injury, impotence, infertility and faecal incontinence. We here report a rare complication in which bladder was accidentally removed during laparoscopic excision of prostatic utricle cyst. To best of our knowledge such a complication has never been reported previously. We also describe the possible cause of this accident and suggest ways to prevent this disastrous complication.
1829 patients underwent radical prostatectomy with pelvic lymph node dissection (RP+PLND) (241 high-risk, 943 intermediate-risk, 645 low-risk). Positive margin rates were 17.8%, 14.8%, and 11.9% in the high, intermediate-and lowrisk groups. Five-year overall survival was 92.5% in lymph node-positive patients and 94.9% in lymph node-negative patients (p = 0.8). Age, prebiopsy prostatespecific antigen, and clinical stage were associated with positive surgical margins in patients with lymph node metastasis (LNM). Recipients of RP+PLND with LNM and positive surgical margins required adjuvant treatment.
PurposeDespite meticulous techniques, surgical complications continue to be problematic in kidney transplant recipients. Role of routine stenting to reduce complications is controversial. In this study, we compare incidence of early urological complications, lymphoceles, urinary tract infections (UTI) and graft function; with or without double-J stenting.Materials and MethodsAll patients who underwent live related donor renal transplantation from February 2014 to February 2016 were included. Transplants prior to February 2015 were without routine stenting; subsequent transplants were with routine stenting. Patients with neurogenic bladder, previously operated bladder and delayed or low urinary output were excluded. Follow-up was for at least three months. Descriptive statistics was performed for all parameters. Chi square test and Fisher's Exact test were used for qualitative variables. For quantitative variables, Mann-Whitney test was used to test median difference and independent samples t-test for mean difference. The p-value ≤0.05 was considered significant.ResultsWe analysed 74 patients (34 stented and 40 non-stented). There was no difference in the incidence of urinary leak, anastomotic obstruction, lymphoceles or UTI (p>0.4 for all comparisons). However, mean estimated glomerular filtration rate at sixth day, 14th day, one month and two months were 76.1 vs. 61.5 (p=0.025), 72.1 vs. 56.6 (p=0.005), 79.4 vs. 63.1 (p=0.002) and 82.0 vs. 63.3 (p=0.001) in the stented versus non-stented groups.ConclusionsPlacement of ureteral stent in renal transplant does not significantly affect the incidence of early urinary complications or UTI. However, graft function is significantly better in stented recipients, at least in the short term.
Malignant mesothelioma (MM) of the tunica vaginalis (TV) is a rare tumor. It is seen in elderly patients, with painless scrotal swelling being the most common presentation. The exact etiology is unknown; a few risk factors have been suggested. Here, we present an uncommon case of MM of TV without any known predisposing factors. We also discuss the possible risk factors, clinical presentation, pathological features and the difficulties in diagnosis, and management of this rare malignancy.
Summary. Aim: To study the correlation of pre-operative neutrophil to lymphocyte ratio (NLR) with pathological stage, Fuhrman grade, sarcomatoid differentiation, tumor necrosis and lymph node positivity and its prognostic role in non-metastatic renal cell carcinoma (non-mRCC). Materials and Methods: This retro-prospective, observational study was done at a tertiary care center in Mumbai, India. All patients with non-mRCC from July 2015 to April 2018 were included. Patients with co-existing systemic infection, prior immunotherapy, and long-term steroids were excluded. NLR closest to surgery, but within one month prior to surgery was used. Patients were stratified as NLR ≥ 3.0 or < 3. NLR was correlated with known prognostic factors by Pearson’s correlation. Results: 113 patients, aged 18–81 years (83 males and 30 females) were included. 75% had clear cell RCC. 62% had stage 1 disease. 58% patients had Fuhrman Grade 2. 10 patients had lymph node metastasis, 6 had sarcomatoid differentiation, 40 had tumor necrosis. The NLR was < 3 in 72 patients. Statistically significant correlation between NLR and tumor stage (p = 0.0054) as well as NLR and tumor necrosis (p = 0.0128) was shown. Conclusions: NLR correlates significantly with higher T stage and tumor necrosis. NLR may be integrated with well-established prognostic markers to improve the accuracy of prognostic scores.
The aim of this study was to compare 18 F-fluorodeoxyglucose positron emission tomographycomputed tomography ( 18 F-FDG PET/CT) scan with computed tomography (CT) scan for detecting recurrence and metastasis in renal cell carcinoma patients. METHODSThis retrospective study included patients from October 2013 to April 2017. Contrast-enhanced CT and PET/CT scans were compared and correlated with histopathology or/and follow-up studies. RESULTSSeventy-six patients, 60 males, were included. Lesions included primary renal, recurrent renal fossa lesions, lymph nodes, and distant metastatic lesions. Of 176 malignant lesions, CT detected 157 lesions; of which, 154 were true positive. Twenty-two false-negative lesions showed abnormal FDG uptake. CT scan had positive predictive value (PPV), negative predictive value (NPV), sensitivity, specificity, and accuracy of 98.0%, 37.1%, 87.5%, 81.2%, and 86.9%, respectively. All 176 lesions were PET/CT-positive. PET/CT had PPV, NPV, sensitivity, specificity, and accuracy of 100% each. The specificity and NPV of PET/CT were superior (P < .05). CONCLUSIONPET/CT appears more accurate than CT scan for detecting metastasis and recurrence in renal cell carcinoma patients. R enal cell carcinoma (RCC) is the most common solid kidney cancer. The incidence in Asian population is 1.1-6.0/100 000. World over, the 5-year survival rate is 68.4%. 1 Localized RCC patients treated surgically usually have favorable outcomes. However, about 20%-40% patients later develop distant metastases. The main aim of postoperative follow-up is early detection of local recurrence and/or distant metastases. Post-surgery follow-up imaging is commonly done with conventional imaging modalities (CIM), mainly computerized tomography (CT) scan. These have certain limitations in assessing local recurrence due to postoperative changes such as fibrosis, adjacent organs occupying the space of the renal fossa, the presence of surgical clips causing metallic artifacts, and other such changes.About one-fourth of the patients are found to be metastatic at initial presentation, with very few (<5%) having single-site metastasis. 2
