BACKGROUND The neurotransmitter pathways in irritable bowel syndrome (IBS) and urinary stone attacks are both related to serotonin, and each disease may be influenced by viscero-visceral hyperalgesia. However, the relationship between urinary tract stone disease and IBS has never been addressed. We aimed to investigate the risk of suffering new-onset IBS after an initial urinary stone attack us...

BACKGROUND Urinary tract stones are increasing in our societies. Similar to the finding in developed countries, majority of our patients have upper urinary tract stones. Urethral stone is an uncommon cause of acute urinary retention. It presents with an emergency management scenario which is compounded by lack of endoscopic facilities in our hospitals. We present the management of urethral ston...

Since the first report in 2005, Roux-en-Y gastric bypass (RYGB) surgery has been linked to a variety of metabolic changes that alter kidney stone risk. The studies with the highest level of evidence, performed in non-stone forming patients before and after RYGB, cite a number of kidney stone risk factors, including a 25% increase in urinary oxalate, a 30% decrease in urinary citrate, and reduct...

PURPOSE To evaluate factors affecting the success rate of stone fragmentation and stone-free rate after extracorporeal shockwave lithotripsy (SWL) in treatment of upper urinary tract stones. MATERIALS AND METHODS A total of 121 patients with upper urinary tract calculi underwent SWL treatment. RESULTS Success rate of stone fragmentation after SWL was 73.6% (89/121). In 89 patients who had s...

PURPOSE Urolithiasis develops more frequently in patients with a family history (FHx). However, little is known about risk factors in stone formers with a FHx. The aim of this study was to examine the clinico-metabolic characteristics of urinary stone formers according to FHx. MATERIALS AND METHODS A database of 1,068 stone formers who underwent a complete metabolic evaluation was reviewed. T...

The study was designed to assess the relationship between glomerular filtration rate (GFR) and urinary stone-forming constituents, and to assess the effect of renal insufficiency on stone recurrence risk in first stone formers (SF). Baseline serum creatinine levels were obtained, and renal insufficiency was defined as creatinine clearance ≤60 mL/min (Cockroft-Gault). This retrospective case-con...

An 89-year-old male presented with dysuria and oliguria. He had a history of benign prostate hyperplasia and neurogenic bladder under long-term Foley catheter use of 10 years. Recurrent urinary tract infections had occurred since then. The laboratory data showed acute renal failure with a blood urea nitrogen (BUN) of 57 mg/dL, creatinine 3.61 mg/dL (baseline renal function 6 months before admis...
