Retrocaval ureter (pre-ureteral vena cava) is an uncommon congenital anomaly that causes ureteral obstruction by external compression. Although right retrocaval ureter is a common entity, left retrocaval ureter is extremely rare. A left retrocaval ureter is usually associated with situs inversus or duplicated inferior venacava (IVC). An isolated left retrocaval ureter with single left-sided IVC is even rarer and only four cases have been reported in the literature. We present images of a case with isolated left retrocaval ureter with a single left-sided IVC without situs inversus.

The results of this study indicated that bipolar resection of bladder tumours have lower incidence of complications especially bleeding, TUR syndrome, obturator jerks and bladder perforation. Bipolar TURBT is safe and efficacious in managing bladder tumours.

ObjectivesTo determine the usefulness of flexible nephroscopy after per-cutaneous nephrolithotomy (PCNL) in detecting residual fragments. Materials and MethodsA prospective study was conducted between January 2018 and December 2019 on patients undergoing standard PCNL using a flexible nephroscope to inspect all the calyces for residual stones. When residual stones were noted, either they were removed by basketing or by performing additional puncture to ensure complete clearance. Patients were followed up for 6 months and at the end of 1 month a plain CT KUB was done to look for residual fragments. ResultsThe study cohort included 212 patients. Significant RFs were found in 28 patients during flexible nephroscopy and in two patients at 1 month follow up CT scan. All patients were stone free during 6 months follow up. ConclusionFlexible nephroscopy during PCNL decreases the chance of residual fragments and thereby reducing the chance of re-procedure rates.

Objective The primary aim of the study was to study the histological changes (Thermal artefacts) noted in the resected specimens between the Monopolar and Bipolar Trans-Urethral Resection of Bladder Tumours (TURBT). Patients and Methods The study was done between March 2012 and Feb 2013. This was a comparative study between Monopolar and Bipolar resection specimens studied for histological changes (Thermal artefacts). Institutional Ethics Committee approval was obtained. Informed consent was taken from all patients. Patients were randomized into two groups, Monopolar Group or Bipolar Group of 50 each to undergo TURBT. Patients either underwent Monopolar or Bipolar TURBT in Glycine and Saline respectively. Results Thermal artefacts were graded according to WHO (World Health Organization) grading system. There was no difficulty noticed during histo-pathological examination of resected specimens. In Monopolar group, there were 27 (54%) grade 2 thermal damage, 17 (34%) grade 1 thermal damage and no grade-3 thermal damage in examined specimen. In Bipolar group, there were 07 (14%) grade 2 thermal damage, 12 (24%) grade 1 thermal damage and no grade 3 thermal damage in examined specimen. Conclusion The degree of thermal damage is much lesser in histological sections of specimen resected using Bipolar energy and interpretation of the grade is easier which is one of the most important prognosticators especially in bladder tumours since high grade lesions are proven beyond doubt to progress and recur.
