RESUMO

INTRODUCTION: Children and adolescents with neurogenic bladder often need clean intermittent catheterization (CIC) over a long period. Our study aimed to identify factors that affect CIC compliance and to determine if CIC compliance affected short-term urological outcomes among patients in Malaysia. STUDY DESIGN: 50 patients aged 2-18 years who perform CIC were included in this cohort study. Patient compliance with CIC was evaluated using the validated Intermittent Catheterization Adherence Scale (ICAS). CIC difficulties were assessed using the validated Intermittent Catheterization Difficulty Questionnaire (ICDQ). Data was obtained on patients' co-morbidity, caregiver factors, socio-economic factors, CIC technique, access to catheters and facilities, urinary tract infections, incontinence, urology tests and treatment. Statistical analysis was performed. RESULTS: Mean age was 6.68 ± 4.34 years. 32 (64%) patients commenced CIC within the first month of life. Mean daily CIC frequency was 4.70 ± 1.33.30 (60%) participants showed strong adherence to CIC. 39 (78%) participants were able to catheterize with no or minor difficulties. Pain (6, 12%), transient blocking sensation (6.12%), and urinary incontinence (3, 6%) were the predominant difficulties encountered. CIC performed by caregiver was associated with improved adherence compared to patient self-catheterization (p = 0.039). The mean age of participants who self-catheterized was 10.7 ± 3.7 years. Strong adherence was also observed among patients who purchased their own CIC catheters (p = 0.007). Participants with lower ICDQ score were more likely to be compliant with CIC (p = 0.007). CIC adherence was not affected by patient's age, gender, co-morbidity, mobility, caregiver factors, socio-economic factors, and age at initiation of CIC. There was no significant association between CIC adherence and febrile urinary tract infections, upper tract deterioration, and bladder stones at 6 months follow-up. DISCUSSION: There is lower CIC adherence when a child begins to self-catheterize and healthcare providers should be alert during this period of transition. Though most patients with spina bifida have decreased urethral sensation, some patients do experience significant pain during CIC which may impact their compliance. These patients would need a review of their catheterization techniques to improve adherence. The limitations of our study are its modest sample size from a single center and short study period. Our study provides insights into the feasibility of instituting CIC in developing countries. CONCLUSION: Strong CIC adherence was observed among patients who were catheterized by their caregiver, purchased their own CIC catheters, and encountered minimal difficulties during catheterization. CIC adherence had no effect on short-term urological outcomes.

RESUMO

Introduction: Urinary citrate is a potent inhibitor of urinary crystallization that is freely filtered in the proximal tubule of the kidney. We aimed to investigate the effect of citrate supplementation with fresh lime juice on the urinary pH and calcium excretion level among healthy individuals compared with that of mist potassium citrate. Method: In this prospective, cross-over single-centre study, 50 healthy medical student volunteers were randomly allocated to two treatment arms. One arm was prescribed with potassium citrate, while the other arm received citrate supplementation with a home preparation of fresh lime juice. The urinary pH and calcium-to-creatinine ratio (uCa/uCr) were measured at baseline and after 7 days of treatment. This was followed by a washout period of 2 weeks, after which each participant crossed over to the other treatment arm, and the urinary measurements were repeated. Results: Potassium citrate significantly increased the urinary pH among all participants, while fresh lime juice did not. Both fresh lime juice and potassium citrate reduced the uCa/uCr, although this effect was not significant. Conclusion: Fresh lime juice is not as effective as potassium citrate in improving the urinary pH and calcium excretion level of healthy individuals. Therefore, it should be used as an adjunct rather than an alternative to potassium citrate.

RESUMO

BACKGROUND: Recent evidence suggested the link between nephrolithiasis and renal function impairment. We aimed to determine the renal function profile and potential factors associated with reduced renal function amongst renal stone formers in multi-ethnic Asians. METHODS: We conducted a cross-sectional study involving patients undergoing percutaneous nephrolithotomy between May 2015 and December 2019. Reduced renal function was defined as having estimated glomerular filtration rate < 60 ml/min per 1.73 m2. Renal stone samples were collected and quantified using infrared spectroscopy. Potential factors associated with reduced renal function including age, ethnicity, educational level, history of diabetes, hypertension, gout, hydronephrosis, serum uric acid level, and type of renal stone were evaluated using univariable and multivariable analyses. RESULTS: A total of 1162 patients from a multi-ethnic population (Malays 67%, Chinese 19%, Indians 13% and indigenous people 1%) with median age of 57 years (Interquartile range 48-64) were enrolled in the study. Almost a third of patients were found with reduced renal function. Multivariable analysis showed that the odds of having reduced renal function increased with age, ethnicity, lower educational level, history of diabetes, hypertension, gout, bilateral hydronephrosis, elevated serum uric acid level and infection stone. CONCLUSIONS: Reduced renal function varies between ethnicities and all age groups of renal stone formers. In addition to age and ethnicity, cardiovascular risk factors including diabetes and hypertension may also need to be taken into account in managing stone patients with reduced renal function.

RESUMO

PURPOSE: We performed intraoperative antegrade venography to assess the prevalence of internal spermatic venous malformations in adolescents with varicocele. MATERIALS AND METHODS: During a 2-year period 58 adolescent males with visible or palpable varicocele underwent antegrade venography before varicocele surgery. Antegrade venography was performed through a scrotal incision. A vein within the pampiniform plexus was cannulated and up to 1.75 mg/kg iohexol 300 mg/ml was injected to outline the entire length of the internal spermatic vein. The radiographs were reviewed and classified according to Bähren and Murray criteria. RESULTS: Of the patients 43 (74.1%) demonstrated parallel duplications (Murray classification type P) of the internal spermatic vein. This rate is higher than the 2% reported based on retrograde venography. Of the patients with parallel duplications 21 (48.8%) showed duplications arising superior to the iliac crest (subtype A) and 22 (51.2%) had a combination of proximal duplications (subtypes B and C). Ten patients (17.2%) had a single internal spermatic vein, 2 (3.4%) had lumbar collaterals and 3 (5.2%) had renal collaterals. CONCLUSIONS: Parallel duplication of the internal spermatic vein is a common finding on antegrade venography. The various levels of duplication need to be identified before treatment of varicocele to maximize the success of the procedure.
