An Interesting Case of Vitamin D-Mediated Severe Hypercalcemia in a Patient With Renal Mass.

Hypercalcemia of malignancy (HCM) is the most common cause of hypercalcemia in hospitalized patients. The pathogenesis of HCM is often multifactorial. One of the rare causes of HCM is extra-renal production of 1,25-dihydroxyvitamin D (or calcitriol), which is often seen in patients with lymphoproliferative malignancies.

Choosing the appropriate size of Amplatz sheath during percutaneous nephrolithotomy-a novel method.

Objective: To choose appropriate size Amplatz sheath during percutaneous nephrolithotomy (PCNL) based on retrograde pyelogram.

Material And Methods: We performed standard PCNL in prone position in 20 patients. All these patients had placement of appropriate size of Amplatz sheath based on retrograde pyelogram images.

Mini access guide to simplify calyceal access during percutaneous nephrolithotomy: A novel device.

Introduction: A precise puncture of the renal collecting system is the most essential step for percutaneous nephrolithotomy (PCNL). There are many techniques describing this crucial first step in PCNL including the bull's eye technique, triangulation technique, free-hand technique, and gradual descensus technique. We describe a novel puncture guide to assist accurate percutaneous needle placement during bull's eye technique.

Aldosterone and cortisol co-secreting bifunctional adrenal cortical carcinoma: A rare event.

Adrenocortical carcinoma (ACC) co-secreting aldosterone and cortisol is extremely rare. We report the case of a 37-yearold female who presented with paresis and facial puffiness. Evaluation revealed hypertension, hyperglycemia, severe hypokalemia and hyperaldosteronemia with elevated plasma aldosterone to renin ratio (ARR).

Single stage ventral onlay buccal mucosal graft urethroplasty for navicular fossa strictures.

Introduction: The correction of fossa navicularis strictures poses a distinct reconstructive challenge as it requires attention to cosmesis, in addition to urethral patency. Different graft and flap based repairs have been described with variable success rates. However, the ideal management remains unclear.
