Spontaneous renal artery dissection is a rare but important cause of flank pain. We report a case of isolated spontaneous renal artery dissection in 56-year-old man complicated by renal infarction presented with flank pain. Doppler study pointed towards vascular pathology. Computed tomography (CT) angiography was used to make final diagnosis which demonstrated intimal flap in main renal artery with renal infarction. [ABSTRACT FROM AUTHOR]

Although transitional cell carcinoma (TCC) is most common histological subtype, calcification in TCC is rarely seen. We report a 64-year-old gentleman who on evaluation found to have calcification in TCC of urinary bladder and its implication on calcium metabolism and management. [ABSTRACT FROM AUTHOR]

Background. To ascertain the validity of kidney paired donations (KPDs) as an alternative strategy for increasing living donor kidney transplantations (LDKTs) in an LDKT-dominated transplant programme since directed kidney transplantation, ABO-incompatible or crossmatch-positive pairs are not feasible due to costs and infectious complications. Methods. This was a prospective single-centre study of 77 KPD transplantations (25 two-way, 7 three-way and 1 six-way exchange) from 1 January 2015 to 1 January 2016 of 158 registered donor recipient pairs. During this period, a total of 380 kidney transplantations [71 deceased donor kidney transplantations (DDKTs), 309 LDKTs] were performed. The reasons for opting for KPD were ABO incompatibility (n=45), sensitization (n=26) and better matching (n=6). Results. KPD matching was facilitated in 62% (n=98) of transplants. In all, 48.7% (n=77) of the transplants were completed in 2015, whereas 13.3% (n=21) of the matched patients were to undergo transplant surgery in early 2016 after getting legal permission. The waiting time for KPD was shorter compared with DDKT. The death-censored graft survival and patient survival were 98.7% (n=76) and 93.5% (n=72), respectively. In all, 14.2% (n=11) of patients had acute rejection. Match rates among sensitized (n=60) and O group patients (n=62) were 58.3% (n=35) and 41.9% (n=26), respectively. Of these, 43.3% (n=26) and 29% (n=18) of transplants were completed and 15% (n=9) and 12.9% (n=8), respectively, are waiting for legal permission. Conclusions. LDKT increased by 25% in 1 year in our single-centre KPD programme. Our key to success was the formation of a KPD registry, awareness and active counselling programs and developing a dedicated team.

In a living donor kidney transplantation ( LDKT) dominated transplant programme, kidney paired donation ( KPD) may be a cost-effective and valid alternative strategy to increase LDKT in countries with limited resources where deceased donation kidney transplantation ( DDKT) is in the initial stages. Here, we report our experience of 300 single-centre KPD transplantations to increase LDKT in India. Between January 2000 and July 2016, 3616 LDKT and 561 DDKT were performed at our transplantation centre, 300 (8.3%) using KPD. The reasons for joining KPD among transplanted patients were ABO incompatibility ( n = 222), positive cross-match ( n = 59) and better matching ( n = 19). A total of 124 two-way ( n = 248), 14 three-way ( n = 42), one four-way ( n = 4) and one six-way exchange ( n = 6) yielded 300 KPD transplants. Death-censored graft and patient survival were 96% ( n = 288) and 83.3% ( n = 250), respectively. The mean serum creatinine was 1.3 mg/dl at a follow-up of 3 ± 3 years. We credit the success of our KPD programme to maintaining a registry of incompatible pairs, counselling on KPD, a high-volume LDKT programme and teamwork. KPD is legal, cost effective and rapidly growing for facilitating LDKT with incompatible donors. This study provides large-scale evidence for the expansion of single-centre LDKT via KPD when national programmes do not exist. [ABSTRACT FROM AUTHOR]

We report for the first time a “giant megaureter” causing symptomatic compression of the contralateral ureter in a 15-year-old girl. Extrinsic compression of the ureter by a contralateral giant hydronephrotic kidney, although rare, has been reported most commonly because of congenital pelviureteric junction obstruction. In this case, the possible etiology of megaureter, the differential diagnosis, and the clinical implications are discussed. [Copyright &y& Elsevier]
