“…66.6% in the Rabat-Salé (Morocco) (Bouatia et al, 2015) and 58.5% in the Middle Atlas (Oussama et al, 2000). Regarding the stone's structure, there two principal types, namely calcium oxalate monohydrate (COM) (Figure 5A), that can be further categorized into five different morphological aspects (subtype types Ia, Ib , Ic, Id and Ie) and characterised by a compact structure, hard and resistant to extracorporeal shock wave lithotripsy (Doré, 2005). While the second type which is calcium oxalate dihydrate or weddellite (COD) (Figure 5B), exhibits 3 subtypes (IIa, IIb, IIc) ( Doré, 2005;Lechevallier et al, 2008;Aguilar-Ruiz et al, 2012;Castiglione et al, 2015;Daudon et al, 2016a).…”

“…This leads to intratubular cystine crystallisation in the excretory tract (Traxer et al, 2008). Cystine stone (Figure 5H; I) is hard and more resistant to ESWL, producing large blocks that can obstruct the excretory tract (Doré, 2005). Its medico-surgical management is essential to limit the risk of lithiasis recurrence and to preserve the patient's renal function (Traxer et al, 2008).…”

Pathophysiological aspects of renal stone formation and stone types

Urinary stone formation is one of the oldest and most widespread diseases known to man. The disease has a multifactorial etiology that includes anatomic, environmental, genetic, infectious, metabolic, nutritional, and most importantly socio-economic factors. It is caused by a biochemical imbalance in urine between stone-forming inhibitors and promotors in a process known as lithogenesis. The mechanisms underlying the formation and development of urinary stones are not fully understood, but it can be said that they generally begin by increased urinary supersaturation of lithiasis promoters in the urine, followed by nucleation and aggregation. Subsequently, the crystals combine with other crystals in solution to form agglomerates that accumulate in the kidney. Free radical-mediated oxalate-induced renal membrane damage promotes crystal retention at the surface of the renal papilla, as well as crystal nucleation at lower supersaturation levels. In addition, stone type identification is of great interest in guiding the physician to an effective diagnosis, which allows to determine the causes in order to treat the disease and prevent recurrence. In this context, this present study reviews current knowledge on the pathophysiological aspects of kidney stone formation as well as the type of stones.

The analgesic effect of inhalational Entonox for extracorporeal shock wave lithotripsy

et al. 2007

View full text Add to dashboard Cite

Extracorporeal shock wave lithotripsy (ESWL) is a non-invasive procedure that allows urinary stones to be fragmented using acoustic shock waves. The impact of the shock waves causes transient stinging pain at the entry site as well as deep visceral discomfort, requiring analgesia during the procedure. The objective of this study was to compare the clinical eYcacy of Entonox and pethidine for pain relief during outpatient ESWL. We randomized 150 outpatients undergoing elective ESWL into three groups of 50 patients, each group receiving inhalational Entonox, intravenous pethidine, or inhalational compressed air during ESWL. Quantitative evaluation of pain was performed according to a visual analogue scale (VAS), before and after the intervention. Analysis of variance (ANOVA) and paired t tests were used to compare VAS scores in the three groups, before and after the intervention. Entonox and pethidine decreased the pain score signiWcantly, while compressed air did not. There was no signiWcant diVerence between pain relief by Entonox and pethidine. This study demonstrates for the Wrst time that inhalational Entonox is an eVective analgesic regimen for ESWL. Entonox can be regarded as an appropriate alternative to analgesics like opioids in relieving pain during ESWL.

IntroductionExtracorporeal Shock Wave Lithotripsy (ESWL) remains the preferred least invasive treatment for urinary tract stones. The main purpose of this study was to compare two treatment modalities for pain control during the ESWL procedure.Material and methodsFrom 2013 to 2014, 220 patients received ESWL for kidney stones. Before the procedure, the weight and height were measured to determine the body mass index (BMI); in addition, oxygen saturation and the pulse of the patients, as well as pain level were determined. The pain control provided included two different methods: diclofenac sodium plus hyoscine-N-butyl bromide in the first group and pethidine plus diazepam in the second group. The pain level of the patients was determined using two different scales: the Wong-Baker and the Visual Analogue scales (VAS). At the end of three sessions, all patients were evaluated for the stone fragmentation rate by plain abdominal X-ray, and the findings were recorded and analyzed.ResultsA total of 220 patients were enrolled in this study. There were 91 patients in the first group (diclofenac sodium + hyoscine-N-butyl bromide) (male/female: 63/28) and 129 (male/female: 83/46) patients in the second group (pethidine HCL +diazepam). The mean age with SD according to each group was 42.03 (±16.43) and 42.56 (±14.23), respectively (p = 0.8). With regard to pain scores (using the Wong-Baker and VAS scales), the responses were significantly lower in the second group (p <0.001).ConclusionsPethidine in combination with diazepam was superior to diclofenac and Hyoscine-N-butyl bromide for pain in patients undergoing ESWL.
