Surgical management of spontaneously ruptured kidney with peritonitis due to neglected renal and ureteric calculi

المؤلفون: Kumar Prem, Prem Pragya, Singh Smita, Kumar Pankaj

المصدر: BMJ Case Rep

الوصف: A 30-year-old woman presented with right-sided abdominal pain associated with fever. Her ultrasound showed right renal calculus with no hydronephrosis along with collection in peritoneal cavity and pouch of Douglas. CT showed ruptured right kidney with multiple renal and ureteric calculi as well as displaced renal calculi in perinephric space and pararenal space. Exploratory laparotomy and right nephroureterectomy were done. Nephrolithiasis with secondary infection makes the kidney fragile due to pathological changes, which may cause rupture of the renal calyces with trivial trauma or may be spontaneous. Distal obstruction by the stone and increased back pressure in the calyces may have added to the spontaneous rupture of the calyx and subsequently renal parenchyma. Management includes early exploration with nephrectomy and it is often life saving.

الوصف: BACKGROUND: Foreign bodies introduced by patients into the bladder and urethra are relatively rare in clinical practice. As a result, there is insufficient information in the scientific literature regarding methods of extracting foreign bodies from the urinary tract. AIM: determination of the optimal methods for extracting foreign bodies from the urethra and bladder. MATERIALS AND METHODS: Foreign bodies of the lower urinary tract were removed in 21 patients: 15 (71.4%) men and 6 (28.6%) women. Foreign bodies were found in the urethra in 7 (33.3%) patients and in the bladder in 14 (66.7%) patients. Removal of foreign bodies from the urethra and bladder was performed endoscopically or during open surgery. RESULTS: Removal of stabbing, cutting and glass objects from the urinary tract in 9 patients was performed during open surgery. Foreign bodies with even smooth edges were removed in 12 patients under urethrocystoscopic control. At the same time, in two patients, coagulated suppositories were first fragmented in the bladder cavity, and then removed in parts. Cystolithotripsy was performed in one patient with a suppository inlaid with calculus before fragmentation. CONCLUSIONS: Foreign bodies with sharp edges or made of glass are safer to be removed from the lower urinary tract during open surgery. Foreign bodies with a smooth and even surface are optimally removed endoscopically. Long and bulky foreign objects that can be fragmented in the bladder cavity are best removed in parts. When foreign bodies are encrusted with large calculi, cystolithotripsy should be performed before their endoscopic extraction.

الوصف: Objective: To define predictors for initial retrograde ureteral stenting (RUS) failure with the need for the percutaneous nephrostomy (PCN) insertion as a drainage method in patients with complicated acute calculus obstructive uropathy. Methods: We undertook a retrospective evaluation of patients who presented with complicated obstructive calculus uropathy (acute renal failure or obstructive pyelonephritis) between January 2016 and January 2020. Patients in whom there was failure to visualize ipsilateral ureteric orifice and those with extrinsic ureteral obstruction were excluded. Patient demographics and radiological data including stone site, hydronephrosis grade, maximum transverse stone diameter, periureteral density (PUD) and pericalcular ureteric thickness (P-CUT) at the maximum transverse stone diameter were assessed using non-contrast computed tomography at the time of admission. Results: The study included 256 patients who were managed initially by RUS trial. Of them, 48 (18.8 %) had RUS failure. The presence of acute pyelonephritis, increased maximum transverse stone diameter ≥ 9.5 mm, P-CUT ≥ 7.5 mm, and PUD at stone level ≥ 17.5 HU were risk factors associated with RUS failure (P = 0.007, 0.002, < 0.001, and < 0.001, respectively). Conclusion: Initial radiological stone and ureteric characteristics, in addition to the clinical diagnosis of obstructive pyelonephritis, can be used to determine PCN insertion as the preferred option over RUS for urinary drainage.

الوصف: Stones disease is our orders crusade with severe morbidity. It is relatively a common disorder affecting 1 to 3 percent of adult in industrialized counties. Renal calculi are much more popular in males than in females in developed countries. 12% of males and 5% to 10% of females who are affected by kidney stones. The urinary calculi increases with age, many usual in the in the age of 30 - 50 age. After the age 60 period, the figure reduction and approaches figure by the ninth decade of the life [1]. Renal calculus incidence in diametric countries varies depending on the areas environmental conditions. In India, the prevalence of Urolithiasias is higher compared to that of grey states in northern states. Renal calculi are many oft seen in warmer climate and summer. Therefore this research to understand the in Kent repertory much useful for the treatment of renal calculi it give a group of remedy which are efficacious in the handling of renal calculi

الوصف: Double J ureteral stents have become a fundamental practice in endo-urology. However, their use is not always without consequences. Fragmentation is a rare and dreaded complication, only a few sporadic cases have been reported in the literature. We are reporting a case of spontaneous fragmentation of double J ureteral stent in a 70-year-old patient who had undergone a simple right-side nephrectomy for the nonfunctioning kidney of lithiasis origin. Two years later, the patient consulted for severe left side loin pain, the biological and radiological based diagnosis was an obstructive renal failure on a single anatomical kidney, the condition was managed urgently by a double J ureteral stenting, and the patient was programmed for rigid ureteroscopy but he stayed out of sight for two years re-consulting after the emission of the distal end of his double J ureteral stent and calculus during urination. The radiographic assessment performed showed a double J ureteral stent fragmented into several pieces. Therapeutic management consisted of extraction of the fragments of the double J stent by ureteroscopy. Keywords: Lithiasis, ureteral catheter JJ, complication, fragmentation, endourology

Aeromedical disposition dilemma: Renal calculi

المؤلفون: P Renjhen

المصدر: Indian Journal of Aerospace Medicine. 63:90-95

الوصف: Renal colic is a condition which causes acute pain of variable intensity. At times, this makes the sufferer visibly powerless and prevents him from performing any skilled task satisfactorily. The most common cause of the symptom is related to a calculus, which is moving inside the ureter inducing ureteral spasm. A military aircrew is declared unfit to fly in case he/she is detected to have renal calculi. At present, with the newer and advanced investigation techniques, the detection of even small renal calculi is possible. This has led to an increase in clinical data. Since the clinical outcome of renal calculi is unpredictable, aeromedical disposition becomes a challenging task for such cases. The paper brings a review of existing disposition guidelines for cases of renal calculi both in the military and civil aviation in different parts of the globe. An attempt is also made to present an approach toward aeromedical certification and surveillance in the form of a proposed decision algorithm to be used by the flight surgeon.

The contact ureterolithotripsy in treatment of ureterolythiasis

المؤلفون: О. S. Vozianov

المصدر: Klinicheskaia khirurgiia. 87:43-46

الوصف: Objective. Аnalysis of the treatment results in patients, suffering ureteric calculi, using the contact ureterolithotripsy procedure. Маterials and methods. In 104 patients with ureteric calculi, in whom ureteroscopy with further laser contact ureterolithotripsy was conducted, symptoms of the disease were analyzed, as well as the diagnostic methods value, peculiarities and efficacy of surgical treatment. Results. In all the patients endoscopic extraction of calculi have been succeeded. Calculus does not cause significant macroscopic changes in ureter, if symptoms, characteristic for ureterolithiasis, persists up to one week. Local edema is formed, if a calculus persists in ureter longer than a week. Long-term (more than two months) local ureteric persistence of calculi enhances the risk of its intramucosal intraureteric «ingrowth» greatly. Conclusion. The contact ureterolithotripsy constitutes a highly effective and miniinvasive method of surgical intervention in ureterolithiasis, guaranteeing high level of postoperative “stone free rate”. Prolongation of the calculi ureteric insertion time without a process of a stone discharge causes the ureteric wall changes, complicating performance of miniinvasive interventions (the contact ureterolithotripsy and a distant shock-wave lithotripsy).

الوصف: Author(s): Kumar Vidhyarthy, Ajit; Hameed, Tariq; Lal, Rohit; Kumar, Awadh; Sahni, Shivanand; Mendoza, Nanse | Abstract: Introduction: Giant urinary bladder calculus in an adult is an uncommon entity. The number of patients with giant bladder calculi has decreased over recent years owing to wider availability of healthcare and better diagnostic modalities.Case Report: We present a case of a young adult without any history of recurrent urinary tract infections or bladder outlet obstruction with giant vesical calculus who presented to the emergency department with gross hematuria, abdominal pain, and dysuria. Investigations revealed a large calculus in the urinary bladder, and suprapubic cystolithotomy was performed. A large stone of 6.5×6×5.5 centimeters, weighing 125 grams, was removed. On follow-up, the patient was free of any symptoms and cystoscopy was normal.Conclusion: Urinary outflow obstruction must be ruled out in all patients with giant vesical calculus. Patients without any predisposing condition should be treated as a separate entity and evaluated accordingly. Multiple surgical treatment modalities are available for bladder calculus patients. Treatment is personalised as per size of stone, number of stones, and associated comorbidities.

الوصف: Background: There is a lack of consensus about whether the initial imaging method for patients with suspected nephrolithiasis should be computed tomography (CT) or ultrasonography. Material and Methods: A total of 130 patients’ USG and CTU were compared for the presence of calculi. Sensitivity, specificity, accuracy, positive predictive value and negative predictive value of USG were calculated with CTU as the gold standard. Results: From the 150 sets of data collected, 45 calculi were detected on both USG and CTU. The sensitivity and specificity of renal calculi detection on USG were 53% and 85% respectively. The mean size of the renal calculus detected on USG was 6.8 mm ± 3.8 mm and the mean size of the renal calculus not visualized on USG but detected on CTU was 3.5 mm ± 2.7 mm. The sensitivity and specificity of ureteric calculi detection on USG were 12% and 97% respectively. The sensitivity and specificity of urinary bladder calculi detection on USG were 20% and 100% respectively. Conclusion: This study showed that the accuracy of US in detecting renal, ureteric and urinary bladder calculi were 68%, 80% And 99% Respectively.

الوصف: Objective: To assess the utility of trans-vaginal ultrasonography in evaluation of non-pregnant sexually active female patients with lower ureteric calculi. Methods: A prospective study was done from January 2015 to December 2017 including non-pregnant sexually active females with suspected ureteric calculus. Trans-abdominal ultrasound was initially done in all patients. In those patients in whom trans-abdominal ultrasound was inconclusive or there was indirect evidence of lower ureteric calculus in form of ureteral dilation but no calculus was evident, trans-vaginal ultrasound was done. The patients with ureteric calculi detected on trans-vaginal ultrasound and kept on conservative management were also followed up with trans-vaginal ultrasound. Non-contrast computed tomography was done in patients with inconclusive trans-vaginal ultrasound. Results: As per the study protocol, 156 out of the total 468 patients evaluated by trans-abdominal ultrasound were eligible for trans-vaginal ultrasound. Trans-vaginal ultrasound was done in 149 patients, as seven patients did not give consent. Seventy-nine patients were detected with a lower ureteric calculus on trans-vaginal ultrasound and 27 patients had gynecologic or other cause for their symptoms. Forty-three patients had an inconclusive trans-vaginal ultrasound of which 36 underwent non-contrast computed tomography, among them only one patient had a lower ureteric calculus. Stone free status could be easily demonstrated on follow-up trans-vaginal ultrasound. Conclusion: Trans-vaginal ultrasound in addition to trans-abdominal ultrasound is a very useful tool in evaluation of sexually active females with suspected lower ureteric calculus.
