Arterial aneurysms (AA) can be classified as true aneurysms, characterized by the persistence of all three layers of the arterial wall with progressive dilation and wall thinning; arterial pseudoaneurysms (APAs) are characterized by a tear in the vessel wall and a periarterial hematoma formation. They could occur due to a visceral, retroperitoneal, or peripheral origin. Most AA/APA are usually found incidentally, and it is imperative to be vigilant in order to diagnose and manage them due to their potentially life-threatening complications...

This review is intended to be a guide for the physician to evaluate and prepare a donor / recipient couple for living kidney transplantation. Although it is intended to be exhaustive, it will not be able to respond at all possible and different cases, but it may apply at most of them. Renal transplantation is considered the choice treatment for patients with chronic renal failure and if the kidney transplant is performed pre-emptive it is associated with better organ and patient survival. The main aim of the program is to evaluate the risks of donor and recipient and to ensure the donor safety and well-being...

Cases: Septic cardiomyopathy is defined as a reversible left ventricular systolic dysfunction. Patients with severe septic cardiomyopathy have a high mortality rate, even if they receive conventional therapy. For those patients, previous reports showed intra-aortic balloon pump (IABP) efficacy. We report two rare cases with IABP introduction leading them to drastic improvement, and survival from severe septic cardiomyopathy. Case 1 is a 78-year-old woman diagnosed with renal calculus pyelonephritis, septic shock, and septic cardiomyopathy...

Itsuro Kazama, Toshiyuki Nakajima
RATIONALE: In patients with bilateral ureteral obstruction, the serum creatinine levels are often elevated, sometimes causing postrenal acute kidney injury (AKI). In contrast, those with unilateral ureteral obstruction present normal serum creatinine levels, as long as their contralateral kidneys are preserved intact. However, the unilateral obstruction of the ureter could affect the renal function, as it humorally influences the renal hemodynamics. PATIENT CONCERNS: A 66-year-old man with a past medical history of hypertension and diabetes mellitus came to our outpatient clinic because of right abdominal dullness...

We describe a 40-year-old living-donor renal-transplant recipient who underwent successful ureterolithotripsy. He had been on hemodialysis for >15 years pre-transplant and underwent ureteroureterostomy along with the surgery. One year post-transplant, ultrasound examination demonstrated hydronephrosis, and CT showed a 6-mm ureteral calculus at the ureteroureterostomy site. No pain and no elevated serum creatinine were present. As the ureter was easily accessed, we performed a ureterolithotripsy, which would confirm whether a suture caused the calculus...

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. METHODS: The mini access guide (MAG) stabilizes the initial puncture needle by mounting it on an adjustable multidirectional carrier fixed to the patient's skin, which aids in achieving the "bull's eye" puncture...

Crossed fused ectopic kidney is an unusual congenital malformation of the urinary tract. This condition is usually identified in the autopsy specimen rather than in general clinical scenario. In this condition, both kidneys are located on one side of the midline and are fused with each other. This condition is generally asymptomatic and usually diagnosed as incidental finding. We came across a case of crossed fused left to right ectopia with inferior infusion with nephroptosis. Generally, in cases of crossed fused renal ectopia, one kidney is lower than the other one but in our report, both kidneys were present at the same level...

Background: Actinomycosis is a condition in which Actinomyces, a normal component of the oral and gastrointenstial flora, becomes pathogenic in the setting of damaged tissue, leading to widespread tissue destruction across fascial planes. Prior literature describing this condition is rare, particularly cases involving the retroperitoneum. In this study, we report a case of retroperitoneal actinomycosis caused by an infected, obstructing ureteral stone. Case Presentation: A 48-year-old woman with a history of substance abuse, malnutrition, and gastric bypass presented to the emergency room with a 3-week history of abdominal pain and fevers...

Bilateral hydroureteronephrosis involves the dilatation of the renal pelvis, calyces and ureter; it develops secondary to urinary tract obstruction and leads to a build-up of back pressure in the urinary tract, and it may lead to impairment of renal function and ultimately culminate in renal failure. Although clinically silent in most cases, it can be diagnosed as an incidental finding during evaluation of an unrelated cause. In a minority of patients, it presents with signs and symptoms. Renal calculus is the most common cause, but there are multiple non-calculus aetiologies, and they depend on age and sex...

The ureterocele is an uncommon congenital anomaly of the lower ureter. Ureterocele with a single pelvicalyceal system, bilateral, and orthotopic variety is less common. Calculi within bilateral ureterocele are a rare occurrence. To the best of our knowledge, only a few similar cases have been reported in the literature. Among the all reported presentations of this type of ureterocele, presentation with Acute Urinary Retention (AUR) has not been described in the literature. We present a case of nine-year-old child having bilateral, single system orthotopic ureterocele with calculi in bilateral ureterocele and presented with AUR due to obstructive bulbar urethral calculus...

BACKGROUND: Uric acid is the metabolic end product of purine metabolism in humans. Altered serum and urine uric acid level (both above and below the reference ranges) is an indispensable marker in detecting rare inborn errors of metabolism. We describe different case scenarios of 4 Sri Lankan patients related to abnormal uric acid levels in blood and urine. CASE 1: A one-and-half-year-old boy was investigated for haematuria and a calculus in the bladder. Xanthine crystals were seen in microscopic examination of urine sediment...

Nephrolithiasis, although a common entity in adults, is less common in children and rare in newborns. The evaluation and management strategies of renal stones in neonates are unclear. We report a rare scenario of renal calculus in a newborn aged 3 days presenting with decreased urine output, fever and crying during micturition. Patient was thoroughly investigated and managed conservatively. Further follow-up showed increase in stone size with recurrent urinary tract infections, hence shock wave lithotripsy was performed to successfully break and clear the stone fragments...

INTRODUCTION: Percutaneous Nephrolithotomy (PCNL) is the treatment modality used for the extraction of large renal stones, or multiple calculi or stones resistant to shock wave lithotripsy. The General Anaesthesia (GA) is the standard modality for PCNL. However, few studies conclude that Spinal Anaesthesia (SA) can be an alternative method of anaesthesia with similar incidence of complications. AIM: In our study we evaluated the feasibility of spinal anaesthesia in terms of intraoperative and postoperative results in patients undergoing PCNL...

Nephropleural fistula following percutaneous nephrolithotomy (PCNL) is a very rare complication and there are only a few case reports available in the literature. We present a case of a 65-year-old male patient with a right staghorn renal calculus and a left upper ureteric calculus who developed a right nephropleural fistula following right-sided PCNL. The patient required intercostal tube drainage. The cause of the fistula was identified to be a superior calyceal infundibular obstruction due to tiny residual stone fragments and oedema, which was endoscopically dilated, and the fistula subsequently healed...
