Abstract	Hematuria following percutaneous nephrolithotomy (PCNL) is a dreaded complication. It necessitates blood transfusion in up to 10% of patients. It may be severe enough in <1% of patients to require angioembolization. We present a 50-year-old male who underwent PCNL for renal pelvic calculus. Since the day of the surgery, he had low-grade fever (100°F) which worsened (102°F) from the 2

Abstract	Renal tuberculosis presenting as renal cyst is rare. Diagnosing renal tuberculosis in pregnancy is usually delayed due to its atypical presentation. We present a 28-year-old postpartum lady who delivered a healthy baby one month back, with history of intermittent fever and chills. She had high spiking fever (102° F), tachycardia (130/min) and computed tomography showed a 16 × 10 cm right renal cyst. Percutaneous drainage was done, 2 litres of thick pus drained and culture was sterile. After three weeks, deroofing and marsupialization of cyst was done. Biopsy revealed granulomatous inflammation composed of epitheliod histiocytes with central incipient necrosis suggestive of tuberculosis. She was treated with anti-tubercular drugs. As the infant was healthy and had no evidence of tuberculosis, no treatment was initiated. The mother is on follow up for 2 years. This case highlights the rare presentation of renal tuberculosis in puerperium.

Abstract	Introduction: Composite reference standard (CRS) is used for diagnosis of urinary tract tuberculosis (UTB). We examined if addition of a new 'component test' as minor criterion in the form of SP could improve the yield. Methods: We identified patients admitted with a diagnosis of UTB from January 2009 to February 2016 from our patient database. We performed the validation of addition of a new 'component' "sterile pyuria" to the existing basic CRS. Results: SP was seen in 50 patients (65.7%). Forty (52.6%) of these patients had one major criterion positive and 10 (13.1%) were diagnosed based on minor criteria. If SP was added as a minor criterion, an additional 8 (9.2%) patients would have been diagnosed based on minor criteria alone without the need for a histopathology. Conclusions: SP could improve the diagnostic yield of existing CRS by 8% with a 70% decrease in reliance on histopathology for diagnosis.

Abstract	Emphysematous pyelonephritis (EPN) is characterized by fulminant necrotizing infection of the kidney and perirenal tissues. Emphysematous pyelonephritis presenting as pneumomediastinum is quite rare. A 65-year-old gentleman presented to us with respiratory failure on ventilator support and uncontrolled sugars. He had fever with chills, abdominal pain, and breathlessness. He was evaluated and computed tomography showed right Huang et al. class 3 EPN with pneumomediastinum. He also had renal failure, respiratory distress syndrome, and metabolic acidosis. Pigtail drainage of right EPN was performed. He succumbed to the disease despite treatment. This case highlights the rare presentation of EPN as pneumomediastinum. How to cite this article: Karthikeyan VS, Mohan V, Narayanan J, Karthikeyan A.

Abstract	Ureteral strictures are usually caused by ureteral calculi, endoscopic instrumentation, infections like tuberculosis, surgical dissection, radiation, malignancy and periureteral fibrosis. A 42-year-old man presented with right loin pain 2 months previously. Contrast-enhanced computed tomography showed right lower ureteral stricture and he was scheduled for right ureteral reimplantation. Intraoperatively, a large hard mass arising from the mesentery of the terminal ileum infiltrating the retroperitoneum and encasing the right external iliac artery, vein and ureter was identified. The mass was resected and psoas hitch was performed over a 5F (26 cm) double J stent. Patient was discharged on tenth postoperative day and is still doing well at 18 months of follow up period. We are reporting this case to highlight the rare possibility of mesenteric fibromatosis and its management.

Abstract	Paraurethral Leiomyomas (PL) are rare benign mesenchymal tumours. Here, authors, report two premenopausal women presenting with obstructive urinary symptoms and a paraurethral vaginal swelling. They had firm mobile paraurethral masses. On magnetic resonance imaging, they were well-defined and no urethral invasion was noted. Surgical excision was performed in both women and histopathological examination confirmed benign spindle cell neoplasm suggestive of leiomyoma. After catheter removal, the patients voided well with maximum flow-rate of 27 mL/second and 25 mL/second respectively. Long-term follow-up is required as late recurrences and transformation to leiomyosarcoma have been reported.

Abstract	Objective: Percutaneous nephrolithotomy (PCNL) carries significant potential for morbidity. Scant data exists on indications and outcomes of second-look PCNL after a failure to completely clear renal stones at the first attempt. We present our experience with second-look PCNL. Material and methods: This was a retrospective record review of 922 patients who underwent unilateral PCNL at a tertiary care center in South India. Baseline patient, stone characteristics and outcomes were compared between 844 patients undergoing primary PCNL and 78 patients requiring second-look PCNL. Results: Increased stone complexity in terms of Guy stone score (GSS), stone size, staghorn calculi and stones in multiple locations were significantly associated with primary treatment failure (p<0.001). Operative time >75 min had a significant association with need for second-look PCNL and complications. Initial PCNL was discontinued due to bleeding (28; 35.9%), pelvicalyceal system perforation (3; 3.9%) and purulent urine leading to urosepsis and hemodynamic instability (2; 2.6%). Staged PCNL was done in 44 (56.3%) patients. During second-look PCNL, new access tracts were necessary in majority (42; 53.9%) of the patients and multiple tracts in 20 (25.6%) patients. In second-look PCNL, complications were comparable to primary PCNL (p=0.289). Conclusion: Second-look PCNL should be advocated in patients where the initial PCNL was discontinued due to bleeding, perforation of collecting system, prolonged operative time (>75 min) and in patients with large stone burden.

Abstract	Purpose: De novo erectile dysfunction (ED) is a known complication after urethroplasty. Incidence and natural history of de novo ED after urethroplasty is underreported. We assessed the incidence of de novo ED after urethroplasty. Materials and methods: Consecutive consenting urethroplasty (n=48) patients aged 21 to 50 years from February 2014 to July 2016 with normal preoperative erectile function as determined by an International Index of Erectile Function-5 (IIEF-5) score ≥22 were included and interviewed at 3, 6, and 12 months. Results: In patients with anterior stricture (n=40), substitution urethroplasty (SU) was performed in 22 patients (55.0%) and end-to-end anastomotic urethroplasty (EEAU) in 18 patients (45.0%). Their mean IIEF-5 score was 24.15±0.8 preoperatively, 20.10±4.2 at 3 months (p<0.001), 22.70±2.3 at 6 months (p=0.0012), and 23.70±1.7 at 12 months (p=0.03), showing a recovery of erectile function with time. All 8 patients with pelvic fracture urethral injury (PFUI) underwent progressive perineal urethroplasty. Their mean IIEF score was 24.0±1.2 preoperatively, 18.8±5.4 at 3 months (p=0.002), 20.9±3.5 at 6 months (p=0.37), and 22.0±1.5 at 12 months (p=0.427). The incidence of ED was similar at 1 year postoperatively between patients with anterior stricture and PFUI and between patients who underwent EEAU or SU for anterior stricture. Conclusions: Incidence of ED at 1 year after PFUI is similar to that after surgery for anterior stricture in patients with normal preoperative erectile function. Among the cases of anterior stricture, recovery was better with SU at 3 months and was similar between SU and EEAU at 1 year.

Abstract	The common causes of irritative voiding symptoms in women include cystitis, vesical calculi, carcinoma bladder and neurologic disorders. Isolated primary vesical amyloidosis (VA) is a rare cause of irritative voiding symptoms. A 50-year-old female, a known case of retroviral disease but not on anti-retroviral therapy, presented with right flank and suprapubic pain for six months, worsening over the past 15 days with dysuria. She also presented with increased frequency of micturition with nocturia and urgency for the same duration. She had no hematuria, other lower urinary tract symptoms or fever. Clinical examination revealed suprapubic tenderness. Ultrasonogram (USG) revealed 1.7 cm vesical calculus. Cystoscopy revealed three spiky vesical calculi. There was a fluffy lesion with mucosal edema over the right lateral wall in the region of the right ureteric orifice, which was biopsied. Biopsy showed fragments of urothelial mucosa with focal areas of ulceration. The underlying stroma was edematous with amorphous pale eosinophilic acellular deposits. Congo red stain showed apple-green birefringence under polarized microscopy suggestive of amyloid. Sections were negative for dysplasia, granulomas or malignancies. VA presents with intermittent gross hematuria in up to 77% patients and irritative voiding symptoms in 23% patients. VA is an uncommon differential diagnosis of cancer urinary bladder, with less than 200 cases reported in the literature. Hence we report this case to highlight that primary VA should also be considered in the evaluation of irritative voiding symptoms.
