REVIEW

Urinary stones consist of two phases-an inorganic (mineral) phase and an organic (matrix) phase. Studies on the organic components of kidney stones have been undertaken later than those on the inorganic components. After osteopontin was identified as one of the matrix components, the biomolecular mechanism of urinary stone formation became clearer. It also triggered the development of new preventive treatments. Osteopontin expression is sporadically observed in normal distal tubular cells and is markedly increased in stone-forming kidneys...

The objective of this study is to understand pathogenesis of melamine-related kidney stone formation. We investigated the characterization of renal tubular cell under exposure to a mixture of melamine and cyanuric acid in vivo. Male Sprague-Dawley rats were separated into two experimental groups. Treatment group was administered daily with a standard commercial diet mixing with melamine and cyanuric acid, and control group was given a normal diet. Rat kidney specimens were stained with hematoxylin/eosin and the crystals were examined using a polarizing microscope...

LETTER

Ammi visnaga was used in Ancient Egypt as an herbal remedy for renal colic. "Khellin", a chemical obtained from Ammi visnaga, was used as a smooth muscle relaxant and has been thought to have pleiotropic effects on urolithiasis. We report a case with multiple ureteral stone passages possibly as a result of medication with an herb preparation, Khellin.

REVIEW
Athanasios Papatsoris, Kemal Sarica
The last decade flexible ureteroscopy has progressed from an awkward diagnostic procedure with limited visualization to a precise surgical intervention allowing access to the entire collecting system. In this review, we present the current status and future perspectives of the ureterorenoscopic management of urolithiasis and non-stone-related upper tract pathologies.

The aim of this study was to reveal the effect of shock wave lithotripsy (SWL) on renal artery contraction-relaxation responses and the relation of this effect with renal hemodynamics. Twenty-four rabbits are divided into six different groups. The first two groups evaluated as the control groups. After isolating the kidneys, we applied phenylephrine (Ph) and acetylcholine (Ach) in the first group and sodium nitroprusside (SNP) and histamine (H) in the second group. In the third, fourth, fifth and sixth groups, 14...

RANDOMIZED CONTROLLED TRIAL
Jian Lin Lu, Qing Lai Tang, Fa De Liu, Ju Hong Hui
We performed a randomized, prospective study to assess the possible role of combined naftopidil and tolterodine for facilitating the spontaneous expulsion of intramural ureteral stones. A total of 76 patients with intramural ureter stones were included in the study from December 2007 to February 2011. Patients were randomized to one of three treatment groups. Group A patients received naftopidil 25 mg/day, group B patients received naftopidil 25 mg/day plus tolterodine 2 mg (twice a day), and group C patients received tolterodine 2 mg (twice a day)...

To evaluate the safety and efficiency of the Aihua (AH)-1 stone removal system (SRS) to treat bladder stones. Thirty five patients with of bladder stones >2 cm and with benign prostatic hyperplasia were treated by transurethral cystolithotripsy with the SRS and TURP. The results in these patients were compared with 14 patients treated with current devices. In the SRS group, 26 patients had a single stone. Average stone size was 3.34 ± 1.03 cm, total operating time was 55.12 ± 19.95 min, and stone removal time was 23...

Medicinal plants are an important source for the therapeutic remedies of various diseases including urinary tract infections. This prompted us to perform research in this area. We decided to focus on medicinal plants species used in urinary tract infections prevention. The aim of our study was to determine the influence of Betula pendula, Equisetum arvense, Herniaria glabra, Galium odoratum, Urtica dioica, and Vaccinium vitis-idaea extracts on bacterial survival and virulence factors involved in tissue colonization and biofilm formation of the uropathogenic Escherichia coli rods...

Crystallization of struvite from artificial urine in the presence of Proteus mirabilis microorganisms depends strongly on pH value. At small value of pH, struvite yields crystals of coffin-like habit with very specific structure. The analysis using scanning electron microscopy shows that the crystals possess well-defined faces, but higher magnifications show very specific structuration as if the crystals were built from small three-dimensional subunits. The possible role of microorganisms in the formation of such a structuration is analyzed...

The first indwelling ureteral splint was described in 1967. A ureteral stent can cause unpleasant side effects, such as urinary frequency, urgency, incontinence, hematuria, bladder pain and flank pain, which have a negative impact on a patient's quality of life. It is necessary to minimize the amount of material in the bladder in order to decrease stent-related symptoms. This study investigated the stent-related symptoms after changing from a double pigtail to a loop-type ureteral stent in the same patient group...

The objective of this study is to analyze the alterations in bone mineral density and bone and calcium-phosphorus metabolism in patients with calcium nephrolithiasis. We designed a study with 182 patients who were distributed among three groups: group O, 56 patients without nephrolithiasis; group A, 67 patients with calcium nephrolithiasis and mild lithogenic activity; and group B, 59 patients with calcium nephrolithiasis and severe lithogenic activity. Metabolic parameters of blood and urine that were related to calcium-phosphorous and bone metabolism and bone densitometry were assessed in all patients...

The use of ureteral stents has become a routine urological practice. There are many different complications with ureteral stent use. One rare complication is knotting, which can be a very difficult condition to treat. We report a case in which a complete knot was found in the proximal part of an indwelling ureteral stent with a proximal ureteral stone.

We reviewed our 6 years of experience with endoscopic holmium: yttrium aluminum garnet (YAG) laser lithotripsy for treatment of urinary stones in different locations in 111 children. A retrospective review was performed on endoscopic holmium: YAG laser lithotripsy procedures performed to treat stones in children between March 2006 and March 2012. In total, 120 laser lithotripsy procedures were performed to treat 131 stones in 111 children (80 males and 31 females; age range, 11 months to 16 years; median age, 6 years)...

The aim of this study was to evaluate the outcome of staged single-tract minimally invasive percutaneous nephrolithotomy (MPCNL) and flexible ureteroscopy as a minimally invasive option in the treatment of staghorn stone in patients with a solitary kidney. A total of 24 patients with staghorn stone in a solitary kidney were treated with single-tract MPCNL and flexible ureteroscopy by a single surgeon. All the patients underwent single-tract MPCNL through a 20 F tract and had most of the intrarenal calculi removed at the first stage...

Extracorporeal shock wave lithotripsy (SWL) is a non-invasive procedure for urolithiasis. Only a very small portion of patients suffer from post-SWL haematoma and most of them have perinephric haematoma formation. We present two patients who developed subcapsular hepatic haematomas after SWL, followed by a review of the literature on the condition.
