Renal Stone management

BACKGROUND: Percutaneous nephrolithotomy is the most commonly used modality for the removal of kidney stones larger than 2 cm in size. Like other stone removal methods, percutaneous nephrolithotomy also has some complications, including bleeding and delayed hematuria. These complications are improved with conservative management and bed rest most of the time. However, it may require more invasive treatments. Angioembolization following an abnormal renal angiography is an efficient treatment modality for delayed hematuria...

INTRODUCTION: Bladder exstrophy-epispadias complex is a rare condition that necessitates numerous surgical procedures during a patient's youth to achieve adequate urine storage and continence. This study aimed to identify the specific needs and functional challenges faced by adults who underwent pediatric bladder exstrophy reconstructions and assessing the management of these issues in an adult population. METHODS: A retrospective chart review was conducted for all bladder exstrophy complex patients who underwent surgery at a young age and were subsequently referred to our center between 2005 and 2020...

BACKGROUND: The aim is to evaluate supine versus prone position in mini-percutaneous nephrolithotomy in pediatric renal urolithiasis management. METHODS: A randomized controlled trial was constructed to evaluate supine versus prone position in pediatric PCNL. Seventy pediatric patients with a stone burden ≥1.5 cm were randomized into two groups. RESULTS: Sixty-three patients were available for evaluation in our study with no significant difference in the perioperative demographic data...

Kidney stone is one of the most frequent disorders of the urinary tract. Once the stone has passed, the management should be oriented on prevention. If changes in lifestyle and diet should be implemented in a true therapeutic education of the patient, prescription of drugs has been recently challenged by the NOSTONE trial. This randomized controlled trial did not show any benefit of hydrochlorothiazide in the prevention of recurrence of kidney stone event in patients with calcium-containing stone. Therefore, prescription of thiazide in the sole purpose of decreasing kidney stone recurrence should be limited and the risk/benefit of this treatment should be carefully balanced for each case...

The lifetime incidence of kidney stones is 6%-12% in the general population. Nephrolithiasis is a known cause of acute and chronic kidney injury, mediated via obstructive uropathy or crystal-induced nephropathy, and several modifiable and non-modifiable genetic and lifestyle causes have been described. Evidence for epidemiology and management of nephrolithiasis after kidney transplantation is limited by a low number of publications, small study sizes and short observational periods. Denervation of the kidney and ureter graft greatly reduces symptomatology of kidney stones in transplant recipients, which may contribute to a considerable underdiagnosis...

BACKGROUND Nephro-colic fistulas are uncommon, generally caused by local inflammation, trauma, or neoplasia affecting the kidney or the colon. Their association with a coralliform stone is described in a few case reports, but their management is difficult and differs quite a lot, depending on the clinical situation. We report an atypical clinical case of a reno-colic fistula associated with a staghorn calculus. This case adds to the literature an iconography rarely found. CASE REPORT A 68-year-old woman presented to the Emergency Department with respiratory symptoms and chronic abdominal pain...

BACKGROUND: Percutaneous nephrolithotomy (PCNL) is the first-line treatment for large renal stones. However, multi-tract or staged procedures may be necessitated in bilateral or anatomically-complex stones to achieve stone clearance. Endoscopic combined intrarenal surgery (ECIRS) integrates the advantages of PCNL and retrograde intrarenal surgery. In this article, we detail a hybrid surgical technique adopted for the management of complex simultaneous bilateral upper urinary tract stones...

Renal hypouricemia (RHUC) is a rare autosomal recessive disorder characterized by impaired renal tubular uric acid reabsorption and abnormally high uric acid clearance, which may be manifested by reduced serum uric acid (SUA) levels and elevated fractional excretion of uric acid (FE-UA >10%). Most RHUC patients are often asymptomatic or have accidentally decreased SUA levels during health examinations, while others develop kidney stones and exercise-induced acute kidney injury (EIAKI). We now report a case of RHUC complicated with an asymptomatic kidney stone, and we identified a heterozygous mutation of c...

Renoduodenal fistulas are a rare and uncommon phenomenon that account for ˂1% of those found between the urinary and intestinal tracts. Precipitation of this pathologic tract can be caused by chronic inflammation, necrosis, or ischemia. This case illustrates a 72-year-old man presenting with flank pain discovered to have multiple renoduodenal fistulas and our approach that led to the resolution of his symptoms. We review the pathophysiology, management, and effects of these fistulous tracts on renal function...

Employing percutaneous nephrolithotomy to manage a complex renal calculus has always been challenging due to the blood transfusion requirement and the frequent necessity of using multiple access tracts. We report a novel treatment modality in the case of a 65-year-old male with a complex, large-volume renal calculus who was successfully treated by vacuum-assisted miniaturized endoscopic combined intrarenal surgery using the combination of a thulium fiber laser in retrograde fashion with a holmium:YAG laser in antegrade fashion...

Objective: Ureteroscopy (URS) is a commonly used procedure for the management of ureteral stones. While elective URS has been extensively studied, the literature on emergency URS remains limited. The aim of the present study is to evaluate the efficacy and safeness of URS performed in emergency settings and to determine the ideal candidates for this type of intervention. Methods: Patients who underwent URS for ureteral stones in a single healthcare unit, "Saint John" Emergency Clinical Hospital, Bucharest, Romania, were included in a retrospective investigation between April 2022 and March 2023...

INTRODUCTION AND IMPORTANCE: Several endoscopic procedures have been performed to clear stones in the kidney. A potential technique called endoscopic combined intrarenal surgery (ECIRS) is a practical option for treating complex kidney stones. Hereby, we report a neglected double j (DJ) stent and recurrent multiple kidney stones treated by ECIRS. CASE PRESENTATION: A 56-year-old female complained of right flank pain one week ago, which worsened within one day before hospital admission...

Introduction: Renal colic is frequently treated with opioids; however, narcotic analgesic use can lead to dependence and abuse. We evaluated use trends of opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) for pain management of kidney stones in United States emergency departments (EDs) from 2015 to 2021. Methods: Kidney stone encounters were identified using National Hospital Ambulatory Medical Care Survey data. We applied a multistage survey weighting procedure to account for selection probability, nonresponse, and population weights...

Background Limited data have explored the efficacy of Super-Mini Percutaneous Nephrolithotomy (SMP) and Retrograde intrarenal Surgery (RIRS) in managing≤ 2 cm renal calculi. This study aims to comprehensively evaluate the safety and effectiveness of SMP compared to RIRS. Method This prospective cohort study investigated 210 patients with renal calculi (≤ 2 cm) undergoing SMP or RIRS, randomly recruited over four years. 51.4% underwent SMP and 48.6% underwent RIRS. Results: The mean patient age was 31...

Extraosseous bone formation of the upper urothelial tract is an unusual phenomenon with limited documentation in the uropathology literature, reported in only 2 clinical series of patients undergoing percutaneous nephrolithotomy for the management of renal stones. While speculations regarding the pathogenesis of this occurrence have been published, heterotopic ossification is still poorly understood. We report the finding of extraosseous bone formation in the renal pelvis of a 30-year-old male patient with a history of kidney stones...

INTRODUCTION: The finding of an asymptomatic stone in the study of a living kidney donor does not necessarily contraindicate donation, however, there is no consensus on the management of these cases. The use of a graft with lithiasis may represent a risk of recurrence in the remaining kidney in the donor and eventual obstructive complications in the transplanted kidney. The objective of this work is to present the usefulness of ureteroscopy (URS) to resolve lithiasis ex vivo before transplantation...

Introduction We explored the viability of simultaneous bilateral endoscopic surgery (SBES) in the prone split-leg position for managing bilateral calculi. Methods We retrospectively reviewed 72 patients who underwent SBES, with procedures involving ureteroscopy (URS) and contralateral percutaneous nephrolithotomy (PNL) simultaneously, in prone split-leg position. Results Operative times averaged 109.38±30.76 minutes, with an average hospital stay of 7.79±3.78 days. Bilateral stone-free rate (SFR) was 70...

Symptomatic urolithiasis is a common cause of emergency department (ED) visits, with non-contrast computed tomography (NCCT) considered the imaging gold standard. According to current guidelines, POCUS is limited to the evaluation of hydronephrosis as a secondary sign of acute ureteral stones. However, the use of POCUS to detect ureteral stones may lead to decreased radiation to the patient and a more rapid diagnosis. This case series describes 10 patients with suspected symptomatic urolithiasis who were diagnosed accurately by emergency physicians using POCUS to detect obstructive ureteral stones...

Peritoneal fistulization of pyonephrosis is an uncommon condition, leading to a generalized peritonitis, considered as extreme life-threatening emergency. Secondary to an obstructive uropathy, increasing intra-renal pressure. In most cases, ureteral stones represent the underlying causes followed by stenosis, tumor, or connective tissue disease. Through this case report, we present a 60-year-old patient with a history of urolithiasis, admitted for an atypical instance of spontaneous renal pelvis rupture in an ectopic right kidney managed surgically...

BACKGROUND: Despite the widespread use of extracorporeal shock wave lithotripsy (ESWL) as a treatment for kidney stones, it is essential to apply methods to control pain and improve patient comfort during this procedure. Therefore, this study aimed to investigate the effect of acupressure at the Qiu point on pain intensity and physiological indices in patients undergoing ESWL. METHODS: This randomized, sham-controlled clinical trial was conducted at the Shahid Beheshti Educational-medical Center in Hamadan City (western Iran) from May to August 2023...
