INTRODUCTION: Reducing the percutaneous nephrolithotomy (PCNL) tract size reduces the morbidity associated with the procedure. Prolonged procedure time is a concern. Modification in technique required is to fragment the stone into smaller particles and remove them using the vacuum cleaner effect. This prospective study compares the efficacy and morbidity of reducing the tract size from the standard 24-16.5 Fr for stones sized from 16 to 30 mm. METHODS: 123 patients were enrolled in this prospective study and distributed into 2 groups based on the tract size used (group A 16...

INTRODUCTION: Percutaneous nephrolithotomy (PNL) is the treatment of choice for larger and complex renal calculi. First step in performing PNL is to obtain access to the renal cavity using either fluoroscopy or ultrasound (US) guidance or a combination of both. Which guiding method to choose is controversial? A systematic review of the literature was performed comparing image guidance modalities for obtaining access in PNL. Evidence acquisition and synthesis: A PubMed, Scopus and Cochrane search for peer-reviewed studies was performed using the keywords "ultrasound" AND "fluoroscopy" AND "Percutaneous nephrolithotomy"...

Introduction: Laparoscopic approach in horseshoe kidney (HSK) is a challenge because of the aberrant vessels, the renal isthmus and the renal ectopia are all unique features of this anomaly encountered during the surgery. We report our single center experience with this technique in managing three patients with HSK. Methods: A total of 15 cases (9 males and 6 females) were operated between June 2011 and December 2016 for various indications. Of these four patients were managed laparoscopically, two patients with HSK had non-functioning renal moiety underwent transperitoneal heminephrectomy...

Background: Drainage of any deep seated abscess often requires placement of catheters along with other conservative measures. These catheters are removed when the drainage volume reduces to clinically insignificant levels. However, if left in situ, there are potential complications. One such complication necessitating additional surgical procedure is highlighted in this case report. Malecot's catheter and children may be more at risk for such a complication. Case Presentation: A 7-year-old girl presented with recurrent episodes of right flank pain associated with high-grade fever with chills for the last 5 months and right perinephric drain in situ...

REVIEW
Gerry K Schwalfenberg, Stephen J Genuis
The scientific literature provides extensive evidence of widespread magnesium deficiency and the potential need for magnesium repletion in diverse medical conditions. Magnesium is an essential element required as a cofactor for over 300 enzymatic reactions and is thus necessary for the biochemical functioning of numerous metabolic pathways. Inadequate magnesium status may impair biochemical processes dependent on sufficiency of this element. Emerging evidence confirms that nearly two-thirds of the population in the western world is not achieving the recommended daily allowance for magnesium, a deficiency problem contributing to various health conditions...

We report a case of 29-year-old woman referred to us for management of refractory epilepsy. Under observation, she was detected to have recurrent hypoglycaemia during the episodes of seizures. On investigation, she was found to have hyperinsulinemic hypoglycaemia. Her triple-phase CT scan of abdomen showed neuroendocrine tumour of pancreatic head, with bilateral renal calculi. Screening of other endocrine glands revealed pituitary microadenoma and parathyroid adenoma on imaging, which was also supported by biochemical and hormonal profile...

Most simple renal cysts rarely require therapy. When it grows to such a large size, regardless of the presence of symptomatology, surgical intervention is required. In this study, we explored a new approach called percutaneous ureteroscopy laser unroofing for treatment renal cysts and evaluated its safety and efficacy. 71 simple renal cyst patients with surgical indications were enrolled, including 6 patients with a peripelvic cyst and 5 patients coexisting ipsilateral calculi. Under ultrasound guidance, an eighteen-gauge needle was placed inside the cyst cavity, and a guidewire was introduced followed by sequential dilation up to 28 F...

Introduction: Flexible ureteroscopy (fURS) is an endoscopic procedure for the minimally invasive treatment of ureteral and renal calculi. Due to improvements in technique and ureteroscopic instrumentation over the past two decades, complications associated with URS are infrequent. However, in the event of an unexpected device malfunction or failure, the operating surgeon must employ prompt, resolute decision-making to resolve any intraoperative complications and avoid significant injury to the kidney or ureter...

Although the second most common malignancy after urothelial carcinoma, squamous cell carcinoma (SCC) of the renal pelvis is a rare entity. It has strong association with nephrolithiasis thus emphasizing prompt treatment of renal calculi. Because of rarity and nonspecific clinical and radiological findings, it mostly presents at pT3 or higher stage. We report SCC of renal pelvis that was missed two times on non-contrast CT scans and was diagnosed incidentally in a nephrectomy specimen. Its prognosis is similar to that of urothelial carcinoma of comparable stage...

BACKGROUND: The abdominal wall is frequently manipulated in a variety of reconstructive procedures, and its anatomy is well described. Our clinical observations, however, contradict the standard depiction of the components of the abdominal wall at various levels - particularly regarding the course of the transversus abdominis muscle (TA). Therefore, we sought to characterize the components of the rectus sheath at various anatomic levels corresponding to surgical landmarks in order to define key points relevant to abdominal wall repair...

BACKGROUND AND OBJECTIVES: Renal stone disease is a common disorder of the urinary tract and also a significant problem because of incidence, recurrence, and severe consequences. The complex pathogenetic mechanisms of renal stone formation involve both biologic and environmental risk factors. The present study was performed to identify the role of these parameters among renal stone patients and normal individuals from a coastal union territory region in South India. METHODS: The authors conducted a case-control study of renal stone disease among outpatient department patients more than 30 years of age using systematic random sampling procedure with 100 study participants (50 subjects for each group)...

Objectives The objective of this study was to identify the renal ultrasonographic (US) findings most strongly associated with azotaemia in cats. Methods US findings in 238 cats with (serum creatinine >180 μmol/l) and 270 cats without azotaemia were compared in a retrospective case-control study. Cats with pre-renal azotaemia or urethral obstruction were excluded. Data extracted from the medical records included age, body weight and body condition score (BCS). Quantitative and subjective US findings were extracted from archived ultrasound images and contemporaneous reports...

Primary hyperparathyroidism is a disease that occurs more frequently than generally thought and is often overlooked. Classical symptoms are bone pain and osteoporosis, renal calculi and peptic ulcers. Many patients are asymptomatic or have unspecific complaints. It is easy to establish the biochemical diagnosis based on calcium and parathormone (PTH) levels and 24-h urine calcium excretion. The most sensitive localization procedures for parathyroid adenomas are sonography and Tc-99(m)-MIBI scintigraphy. The indication for surgery is undisputed in symptomatic patients; however, there is controversy concerning patients without classical symptoms...

OBJECTIVE: To analyze the results of flexible ureterorenoscopy (F-URS) with holmium laser in the treatment of kidney stones with ectopic and fusion anomalies (horseshoe kidney and rotation anomalies). METHOD: We reviewed data from 13 patients with fusion and ectopic renal anomalies that underwent F-URS from April 2011 to April 2017. We analyzed demographic and clinical data (age, gender, BMI, anatomical abnormality, location and dimension of the renal calculi) and perioperative data (method of treatment, stone-free rate, number of days with DJ catheter and perioperative complications)...
