Multiple studies in the current literature have shown that the number of positive lymph nodes predict recurrence free survival (RFS) and overall survival (OS). The objective of this present retrospective analysis is to authenticate the use of LND as a predictor of RFS and OS after ILND. Methods: Our institutional penile cancer database was analyzed for patients who underwent ILND from January 2000 to May 2008. Survival analysis was performed using the KaplanMeier method to determine RFS and OS. Two-sided p values <0.05 were considered significant.

We are describing here a rare case of renal mass with teratoid histology in an adult female. The tumor was removed by enucleation. Grossly, the removed tumour was well-encapsulated homogeneous mass measuring 2 x 3 cm. On microscopy triphasic patterns of WT and prominent heterologous components were seen, including rhabdomyoblasts, bone, cartilage, and various types of mature epithelium. This is probably third reported case of a teratoid WT occurring in an adult kidney.

Although histologically grouped under benign, they often clinically mimics as intrascrotal malignancy. Imaging studies and histopathological examination are of paramount importance in establishing the true nature of this disease. Because these tumors are benign, instead of radical orchiectomy, testes sparing surgery is contemplated to preserve fertility in these patients.

DM usually inflicts major insult to almost all organ systems of the body, including the urinary tract. However, there is a dearth of literature on potential hazardous effects of DM on the urinary tract in a particular population. Considering its negative impact on the quality of life, particularly among the growing elderly population in India, we performed literature search through PubMed and unbound Medline database using the terms “diabetic cystopathy,” “diabetic complication urinary tract,” “diabetic urethropathy,” and “diabetic bladder dysfunction” to study the current understanding on the pathophysiology of diabetes induced on the lower urinary tract dysfunction. All the literature based on DM relevant to lower urinary tract dysfunction were studied, and a comprehensive overview of the current understanding of the pathophysiology of diabetes induced on the lower urinary tract dysfunction is provided. These results will facilitate the future directions for research and clinical care of patients with DM-induced lower urinary tract dysfunction. In conclusion, the long-term hyperglycemic state may result in structural and functional changes in urinary bladder and urethra, contributing to deterioration of lower urinary tract coordinated function.

The literature suggesting association of elevated inflammatory biomarkers in patients with urolithiasis is very scarce. Therefore, present study aimed to compare association of inflammatory biomarkers with urolithiasis. Methods This prospective study compared patients age > 14 years with kidney, bladder, ureter stones and no other systemic disease (test group) with healthy controls (control group). Baseline characteristics and routine blood tests were recorded. Primary endpoint was to diagnose the effect of biochemical parameters in stone prevalence. Results A total of 399 populations categorized into two groups: test group (n = 358) and control group (n = 41). The median age was 47.0 years in the test group and 48.0 years in the control group. The proportion of men was more than women in both the groups. The median C-reactive protein level and red cell distribution width (RDW...

PCNL also accomplishes higher stone-free rates and requires fewer auxiliary procedures than shock wave lithotripsy (SWL) and ureterorenoscopy (URS) for renal stones between 1–2 cm. There are different intracorporeal lithotripter devices available. This study aims to compare the efficacy and safety of holmium laser, pneumatic lithotripsy and Shock Pulse in PCNL. Materials and MethodsA prospective randomized study was performed in Gauhati Medical College & Hospital, Guwahati, Assam, India, between October 2016 to November 2018. Patients of renal calculi and upper ureteric calculi less than or equal to 2.5cms and functioning kidney on the ipsilateral side were included. 300 patients were randomized according to a random number generator. In the holmium laser, pneumatic and Shock Pulse groups’ number of patients was 96, 102, 102 respectively. Stone di...

The aim of present study was to find the relation between score of the EGFR in Transitional Cell Carcinoma (TCC) of bladder and its various prognostic variables.Methods: This is a retrospective study conducted in Dept of Urology, Gauhati Medical College Hospital between Dec 2016 and July 2017. Forty cases of TCC bladder that were operated either by TURBT or radical cystectomy have been taken. However, patients with CKD, pre-existing systemic disease and UTI were excluded from the study. Presence of EGFR and its score were analysed. The rating was done as 0 (non-immunoreactive), 1+ (weak), 2+ (moderate) and 3+ (strong). The correlation between EGFR score and the various factors like age, sex, stage, size of tumour, presence of CIS, tumour grade, muscle invasion, number of tumours and type of stalk were evaluated statistically using c...

A patient underwent ileal ureteral substitution using a reconfigured ileal segment of Yang-Monti principle in our clinical centre. Authors report a case of a 41year old male involved in a homicidal stab injury with isolated renal pelvis injury underwent Thompson’s renal capsular flap repair. After 6 weeks, double J (DJ) stent was removed and following that patient developed urinoma. Percutaneous drain was placed to drain urinoma on emergency basis and again 6 Fr DJ stent was inserted but patient had recurrent fever and chills. On CECT evaluation authors noticed that DJ stent was outside the upper urinary tract. And then patient was re-explored where authors found 6 cm stricture of the proximal left ureter. A reconfigured small bowel tube was interposed between inferior calyx and proximal ureteral stumps. This technique offers certain distinct advantages. A short il...

The choice of surgery is based on the stricture location, length of the stricture and etiology. Buccal mucosal graft (BMG) urethroplasty with Asopa and Kulkarni techniques, revolutionized the approach to anterior urethral stricture repair. Objective of the study was to compare both the dorsal onlay BMG urethroplasty technique of Kulkarni and the dorsal inlay BMG urethroplasty technique of Asopa for the management of long anterior urethral stricture.
Methods: From January 2015 to October 2019, a total of 90 patients with long anterior urethral strictures were randomized into two groups. Group A (42 patients) managed by Kulkarni technique. Group B (48 patients) managed by Asopa technique. BMG urethroplasty was considered successful if no further procedure required postoperatively with maximum flow rate >15 ml/s during the follow-up period.Results: The success rate in group A and B were 80.9% and 87.5%, respectively. The...

Paucity of such tumors makes them a subject of interest worldwide. As per European Association of Urology, since ccRCC is a non-designation, they included all non-clear cell RCC under one nomenclature as rare kidney cancer (RKC). The objective of our study is to determine influence of inflammatory markers on the prognosis of RKC.Methods: Data from cancer registry was retrieved and all rare kidney cancer patient’s data were analysed particularly the markers of inflammation like neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), systemic inflammatory immune index (SIII) and C reactive protein (CRP) to albumin ratio and their probable influence on cancer free survival (CFS), progression free survival (PFS) and overall survival (OS).Results: Data of...

Patients with clinically bothersome LUTS suggestive of BPH not relieved with medical treatment benefit from transurethral resection/vaporization of prostate using various energy sources. Monopolar TURP has been the main form of treatment for many years in men with BPH and remains the gold standard against which other treatments are evaluated. The aim of this article is to review the role of m-TURP in contemporary BPH management.Methods: This retrospective study included 275 patients with bothersome LUTS and histologically confirmed BPH, who underwent m-TURP at Deprtment of Urology and Renal Transplantation between July 2010 and July 2015 and were in follow up for at least 24 months in the Urology OPD. The most frequent indication (50-60%) for TURP is LUTS ref...

Metastasis to cervical lymph nodes is primarily from sites in head and neck. About 1% of all malignant cervical adenopathies are encountered as metastasis from remote primary site. We present here our experience of four cases in last five years. Patients presented as cervical lymphadenopathy with unknown primary, which on evaluation was found to be of genitourinary source from different sites. It is a single centre retrospective study. We reviewed cancer registry. We found four cases of genitourinary cancer with cervical lymph node metastasis. Patients presented as cervical lymphadenopathy of unknown primary. Among those one papillary renal cell cancer with rhabdoid differentiation, one testicular cancer, two prostate cancer. One case was a 67 year male patient, who revealed papillary renal cell carcinoma with rhabdoid features. Another patient was a male of 31 years, who had left testicular mass with r...

These injuries are associated with other solid or hollow viscous injuries or fractures of transverse process of the adjoining vertebrae. We report a case of a 41year old male involved in a homicidal stab injury. This patient presented with pain abdomen and protrusion of omentum at wound side while CECT whole abdomen revealed extravasation of contrast from left renal pelvis at L3 vertebral level into retroperitoneum with localized collection. He underwent exploratory laparotomy which revealed isolated (Grade III) injury in left renal pelvis with no associated renal parenchymal injury.
