Removal of Large Urinary Stone Using Percutaneous Nephrolithotomy in a Patient with Crohn's Disease

Extraintestinal manifestation (EIM) of inflammatory bowel disease (IBD) is approximately 36%. Of genitourinary complications as an EIM of Crohn’s disease (CD), nephrolithiasis is the most common urinary complication in patients with CD. CD patients have been shown to have decreased urinary volume, pH, magnesium, and excretion of citrate, all of which are significant risk factors for nephrolithiasis. Genitourinary complications often occur in case of a severe longstanding disease and are associated with, the activity of bowel disease, especially in those who have undergone bowel surgery. As uncontrolled nephrolithiasis could impair renal function as well as adversely affect quality of life, proper monitoring, early detection, and prevention of the occurrence of urologic complications in CD is crucial. Few data are available about urolithiasis in patients with CD. Herein we report a case of a successful removal of a 2.7 cm calcium oxalate stone using percutaneous nephrolithotomy from a patient with long-standing CD with a previous surgery for small intestinal and colonic stricture.

An Assessment of Antimicrobial Prescription Pattern among Surgical Patients: A Hospital Based Cross Sectional Descriptive Study

Introduction: Antimicrobials are used before, during and after surgery to prevent infections to decrease the duration of hospital stay, increase surgical outcomes and reduce health-related costs. There is inadequate evidence to determine the effective group of antimicrobials to be used in surgical prophylaxis in our settings. Methods: A hospital-based cross-sectional descriptive study involving antimicrobial prescriptions pattern among 223 surgical patients was undertaken. Information on patient’s demographic variables, diagnosis, type of surgery and wound, perioperative antimicrobial use, postoperative complications and number of antimicrobials prescribed from the essential medicine list were recorded. The antibiotic prescription patterns were assessed based on a comparison with international and national guidelines. Results: Among 223 patients, males were predominant with an overall mean age of 42.77 years. The total number of diagnoses was 30, the commonest being appendicitis (21.52%), urinary stone disease (15.69%), hernia (13.90%) and cholelithiasis (11.65%). The common surgeries performed were emergency appendectomy, hernioplasty and laparoscopic cholecystectomy. Eighteen types of drugs from seven different antimicrobial groups were used perioperatively, out of which 73% and 83% were prescribed based on international and national guidelines respectively. Conclusion: The most common antimicrobial used was third-generation cephalosporin. The postoperative antimicrobial rate was found higher compared to preoperative and intraoperative prescriptions and for a longer duration compared to national and international guidelines.

Correlation between Ion Composition of Oligomineral Water and Calcium Oxalate Crystal Formation

The ion content of drinking water might be associated with urinary stone formation, representing a keystone of conservative nephrolithiasis management. However, the effects of specific ions on calcium oxalate crystal formation and their mechanism of action are still highly controversial. We report an investigation of the effects of oligomineral waters with similar total salt amount but different ion composition on calcium oxalate (CaOx) precipitation in vitro, combining gravimetric and microscopic assays. The results suggest that the “collective” physicochemical properties of the aqueous medium, deriving from the ion combination rather than from a single ionic species, are of importance. Particularly, the ability of ions to strengthen/weaken the aqueous medium structure determines an increase/decrease in the interfacial energy, modulating the formation and growth of CaOx crystals.

Giant urethral stone with diverticulum; a case report

Urethral calculi are rare and represent 1-2% of all urinary stone diseases. Rarely, calculus grows to large size and are labeled as a "giant urethral calculus". A 75-year-old male came to the OPD of Madinah Teaching Hospital Faisalabad with a chief complaint of suprapubic pain, penile pain, and hard mass on the left side of the scrotum and anterior perineum. The patient had a significant history of undergoing debridement for Meleney's and Fournier's gangrene, along with suprapubic cystostomy done about 1.5 years back. Physical examination revealed a solid mass with dimensions 6x7 cm on the left side of the scrotum and anterior perineum (left periurethral area). Open surgery was performed. A huge stone, 6x6cm, was removed. Diverticulae were excised, and urethroplasty was performed. A catheter was removed on the 21st postoperative with a satisfactory urinary stream.

A population-based retrospective cohort study analyzing contemporary trends in the surgical management of urinary stone disease in adults

Introduction: We aimed to review the trends and incidence of surgical intervention for adults with upper urinary tract stones in Ontario, Canada, and to hypothesize potential causes for the observed changes. Methods: We carried out a retrospective, population-based cohort study using administrative databases held at the Institute of Clinical Evaluative Sciences (IC/ES) to identify all adults (≥18 years) who underwent surgical treatment for urolithiasis, defined by records using a combination of both hospital and physician billing from 2002–2019. Descriptive statistics were used to summarize baseline patient demographics, and surgical trends were analyzed using the Cochrane-Armitage test for trend. Results: From 2002–2019, 140 263 patients were treated surgically for urolithiasis. During this time period, the total number of surgically treated stone disease increased by 80.5%. By type of procedure, percutaneous nephrolithotomy (PCNL) increased by 187% and ureteroscopy (URS) increased by 158%, while the number of shockwave lithotripsy (SWL) declined by 31.4%. The adult population in Ontario in the years evaluated grew by 24.4%. The number of surgical procedures per 100 000 people over this time grew by 45.3%. For every 1% increase in the population, there was a 2.6% rise in stone-related surgical procedures. Conclusions: The number of stone-related surgical procedures performed rose significantly and cannot be accounted for by population growth alone. This rise was proportionally larger in the female population, further supporting a narrowing of the gender gap in urinary stone disease. The reasons for the increase are likely multifactorial and may imply an increasing incidence of surgically treated stone disease. The change in the proportion of URS and SWL performed may demonstrate a continued shift in surgical preference or may be reflective of resource limitations and availability. The increase in PCNL volumes may also suggest a greater complexity of cases. These findings should be considered for future resource planning and require further study.

Management of Mutrashmari (Urolithiasis)- A Case Report

Ashmari comes under Mutravaha srotovikara and Ashtamahagada as described in Susruta Samhita.The prevalence of urinary stone is approximately 3 to 5% in general population and is increasing across the world mainly due to metabolic derangement, global climatic changes. Acharya Susruta said, before attempting surgical procedures one should try with oral medications like ghrita, paneeyakshara, taila etc. which possesses properties like chedana, lekhana, bhedana and mutrala for facilitating the disintegration of urinary stones. A 39 years old male patient came to OPD at Taranath Govt. Ayurveda Medical College, Ballari on 20 May 2021 presented with complaints of pain in right flank region, pain in right loin radiating to groin, burning micturition, orange coloured urine for 2 days, diagnosed as Urolithiasis and advised for surgery. He visited our hospital to avoid the surgery and for the treatment of the same. Kokilaksha Paneeya Kshara and Punarnavadi Kashaya given to patient for 28 days and got relief from symptoms. Key words: Ashmari, Ashtamahagada, Paneeya kshara, Punarnavadi Kashaya.

Three-channel ion chromatograph for improved metabolic evaluation of urolithiasis

Background Urolithiasis is a multi-etiological disease resulting from a combination of environmental and genetic factors. One of the most challenging aspects of this disease is its high recurrence rate. For most patients, an in-depth metabolic evaluation may reveal the presence of urinary stones. The fact that different urinary stone-related compounds (USRCs) are measured by different methods renders the metabolic evaluation of urolithiasis quite tedious and complex. Methods A three-channel ion chromatograph (IC) that automatically measures the concentration of common metabolic indicators of urolithiasis in urine (i.e., oxalate, citrate, uric acid, calcium, and magnesium) was developed to improve the efficiency. To validate its precision and specificity, standard curves were prepared using working solution of these indicators. 100 standard solutions of these indicators were measured with our new IC and three other ICs as the control instruments; analyte concentrations in 100 24-h urine samples from volunteers and 135 calculi patients were also measured. Results All analytes had good linear relationships in concentration ranges of 0–10 mg/L. The precision experiments in the standard and urine samples showed that the measurement errors of the newly developed IC were all less than 5%. In urine, the recovery rate ranged from 99.6 to 100.4%, the coefficient of variation ranged from 1.39 to 2.99%, and the results matched between our newly developed IC and the control ICs. The results of the efficiency test showed that we can finish the analysis at the average number of 14 people per day with the new IC. While the average number in the control group is 3.85/day (p = 0.000). Conclusions Overall, this multi-channel system significantly improves the efficiency of metabolic evaluation while retaining accuracy and precision.
