INTRODUCTION For small renal calculi (< 2 cm) the currently available treatment options include extracorporeal shockwave lithotripsy (ESWL), retrograde intrarenal surgery (RIRS) and standard/mini percutaneous nephrolithotomy (PNL). A new method, microperc, has therefore been developed, in which a smaller tract size and smaller instruments were used. AIM To present our clinical experiences wit...

OBJECTIVE To review our experiences with diagnosis and management of symptomatic nephrolithiasis complicating pregnancy and to ascertain the efficacy of renal sonography for initial diagnosis compared with plain x-rays or single-shot intravenous pyelography. METHODS Perinatal outcomes were evaluated for all pregnant women admitted to Parkland Hospital for nephrolithiasis from 1986 to 1999. Di...

UNLABELLED Spinal cord injury patients may develop proteinuria as a result of glomerulosclerosis due to urosepsis, hydronephrosis, vesicoureteric reflux, and renal calculi. Proteinuria in turn contributes to progression of kidney disease. We report one paraplegic and two tetraplegic patients, who developed recurrent urine infections, urinary calculi, and hydronephrosis. These patients required ...

Purine nucleotide degradation refers to a regulated series of reactions by which human purine ribonucleotides and deoxyribonucleotides are degraded to uric acid in humans. Two major types of disorders occur in this pathway. A block of degradation occurs with syndromes involving immune deficiency. myopathy or renal calculi. Increased degradation of nucleotides occurs with syndromes characterized...

OBJECTIVE The aim of the study was to determine if the degree of hydronephrosis on focused emergency renal ultrasound correlates with kidney stone size on computed tomography. METHODS A retrospective study was performed on all adult patients in the emergency department who had a focused emergency renal ultrasound and ureterolithiasis on noncontrast computed tomography. Severity of hydronephro...

c Abstract: The most common form of renal ectopy is pelvic kidney and treating stone disease and achieving complete stone clearance in such anatomical anomaly is difficult. We report a case of patient with pain in left iliac fossa and evaluation revealed left pelvic kidney with multiple renal calculi. We describe the successful management of calculi with laparoscopic assisted Percutaneous Nephr...

bladder calculi, a rare condition in the pediatric population, occur most commonly as a result of either migration from the kidney or urinary stasis in the bladder. we report the case of a 3-year-old boy with recurrent urinary tract infections (uti) secondary to bladder calculi formation on the sutures from a previous herniorrhaphy.a 3-year-old boy with previous history of herniorrhaphy present...

BACKGROUND Renal squamous cell carcinoma is a rare neoplasm with poor prognosis. Chronic irritation from nephrolithiasis and/or pyelonephritis is the leading cause. CASE PRESENTATION We described a 51-year-old male patient who was admitted because of left flank pain. Ultrasonography showed a renal cyst containing calculus. However, contrast-enhanced ultrasonography and CT scan revealed an irr...

PURPOSE Tubeless percutaneous nephrolithotomy (PNL) remains a challenging technique for the surgical treatment of staghorn renal calculi. Our study was designed to compare surgical outcomes between conventional and tubeless PNL. MATERIALS AND METHODS We retrospectively enrolled consecutive patients who underwent conventional or tubeless PNL under general anesthesia performed by a single surge...

hematuria is one of the most common genitourinary findings in children and extensive evaluation frequently fails to establish its etiology. ‎a known cause of hematuria in children is nephrolithiasis. ultrasound is a good method for diagnosis, but calculi less than 5 mm in diameter may not have a posterior shadow. calyceal microlithiasis (cm) is characterized by presence of hyperechogenic spots ...
