“…Climate with such conditions plays a major role in the incidence of urolithiasis (Al-Naam et al 1987;Freundlich et al 1982;Rizvi et al 2002;Sobhi 2006). The increase of animal protein intake and carbohydrate foods leads to an increase of oxalate and urate stones in patients (Robertson et al 1978;Robertson and Peacock 1982;Parks et al 1994;Sobhi 2006).…”

“…Countries in the Middle East (especially Jordan) are categorized in the Afro-Asian stone belt and fall within the tropical Fig. 1 Ideal size of two representative samples of urinary stones, ranging from the size of sand particles to golf balls and subtropical regions that (Robertson et al 1980;Sobhi 2006) have consistently reported a high incidence of urolithiasis (Rizvi et al 2002) with a high incidence among children (Freundlich et al 1982;Dajani et al 1988). A specific problem of the Middle East region is the neglected asymptomatic large and staghorn calculi that present with renal failure (Gupta et al 1985;Husain et al 1995).…”

Urinary stone diseases are increasing in the Middle East. The majority of urinary stone cases are found in the northern part of the country. Stone samples taken from patients living in the Irbid area were collected from Princess Basma Hospital. The present study concentrates on the mineralogical and chemical composition of the urinary stones and on the effective environmental factors that assist in developing the different types of urinary stones. Using X-ray diffraction techniques, the mineralogical composition of the urinary stones was found to be as follows: oxalate, cholesten, and uric acid, with cystine stones occuring more frequently than the others. Cholesten and calcium oxalate stones are the most dominant types of stones. Calcium oxalate is the most common type of oxalate stone. Calcium oxalate is represented in: whewellite, wheddellite, and calcium carbonate oxalate hydrate minerals, in addition to other minerals such as brushite, ammonium phosphate, vaterite, valleriite, and bobierrite from other types of stones. Bobierrite (phosphate group) is a new mineral reported in urinary stones, and this has not been determined in any previous study worldwide. Apatite (calcium phosphate) is deduced using scanning electron microscope (SEM) images. The SEM technique determined crystal forms and systems, shapes, morphological features, and the names of the minerals forming urine stones, while optical properties are studied by polarizing microscope. X-ray fluorescence technique determined the concentrations of major and some trace elements. It revealed that Ca is the main constituent of the urinary stones, especially those composed of calcium oxalate and calcium phosphate. The concentration of trace elements was Ba = 1.57, P = 3.61, Fe = 1.78, S = 2.08, Zr = 4.63, Mo = 3.92, Cu = 1.89, Co = 1.56, and F = 4.2% and was higher in the urinary stones of Jordanian patients than in foreigners in the country. Questionnaires completed by patients suggest that the most significant factors directly effecting the formation of stones are water, climate conditions, food rich in protein and rich in different chemicals. Moreover, some drugs and diseases might also help in developing other stones.

In this study we aimed to determine the effects of previous open renal surgery, percutaneous nephrolithotomy and extracorporeal shockwave lithotripsy (ESWL) on the results and complications of subsequent percutaneous nephrolithotomy (PCNL) in pediatric patients. We reviewed the files of all 105 patients with 116 renal units (RU) undergoing PCNL at two main institutions between December 2000 and February 2014. The 116 RUs were divided into four groups: primary PCNL patients with 44 RU (37.9%) were categorized as group 1, 29 RU (25%) with a history of failed ESWL on the same side were categorized as group 2, 23 RU (19.8%) with previous PCNL surgery were categorized as group 3 and 20 RU (17.2%) with open renal surgery were categorized as group 4. Patient characteristics, mean operative time, mean fluoroscopy time, time to access the collecting system, hemoglobin change, number of more than 1 access, stone-free rates, postoperative hospitalization time and complications in four groups were compared. There were no differences between the groups in age, sex, mean stone size and stone laterality. Mean operative time, mean fluoroscopy time, time to access the collecting system, hemoglobin change, complication rates, number of more than one access hospitalization times were similar in the each group (p > 0.05 for each parameter). The stone-free rates after PCNL were 81.8% in group 1, 79.3% in group 2, 78.3% in group 3 and 80 % in group 4 (p = 0.67). Percutaneous nephrolithotomy is effective and safe in children who have previously had open nephrolithotomy, history of ESWL or PCNL without no more complications than are seen with primary PCNL of kidneys and with similar success rate.

RESULTSThere were 30 renal units in 29 children (median age 3.8 years, range 1.4-5). Because of poor growth the mean ( SD ) body weight of the children was only 12.2 (2.8) kg, which is near the 50th percentile for children of mean age 3.5 years. The median (range) stone burden was 2.35 (1.3-6) cm; 60% of the patients had single stones while 28% had more than five. There were five staghorn stones. All PCNL was primary and with one puncture, using a 17 F angled nephroscope; stones were fragmented using a pneumatic lithoclast. After PCNL stones were completely cleared in 60% of the renal units, which increased to 100% after combining it with extracorporeal shockwave lithotripsy. The median (range) follow-up was 24.9 (4-51) months; the overall complication rate was 6%. In the long follow-up hypertension was not detected in any child and isotopic renograms in 17 kidneys detected no new scarring or loss of renal function. CONCLUSIONPCNL is a safe and effective for treating renal stones in very young children. KEYWORDS PCNL, renal stones, pre-school children OBJECTIVETo review our experience of percutaneous nephrolithotomy (PCNL) in children before school age, and determine its efficacy and safety in this age group. PATIENTS AND METHODSThe records of children aged £ 5 years undergoing PCNL were reviewed. Variables assessed included stone number, size, location and type. The PCNL puncture site and number were also recorded. We reviewed stone clearance with PCNL, ancillary procedures used, complication rates and follow-up status of the children.
