Distintos enfoques adoptados por los médicos para tratar la nefrolitiasis en pediatría: estudio basado en una encuesta / Different approaches among physicians to treat pediatric stone disease: a survey-based study

Introducción. Los pediatras, cirujanos y subespecialistas, como urólogos y nefrólogos pediátricos, participan en el diagnóstico y tratamiento de la nefrolitiasis pediátrica. El objetivo fue determinar los enfoques de distintas disciplinas y evaluar las diferencias en sus protocolos de diagnóstico y tratamiento habituales.Población y métodos. Cuestionario administrado a participantes de sesiones sobre nefrolitiasis en congresos nacionales en 2017 para evaluar las rutinas de diagnóstico y tratamiento de la nefrolitiasis entre distintas especialidades (cirujanos y pediatras) y subespecialidades (nefrólogos pediátricos y urólogos pediátricos).Resultados. Se analizaron 324 cuestionarios de 88 pediatras, 121 urólogos, 23 cirujanos pediátricos, 54 nefrólogos pediátricos y 38 urólogos pediátricos. Ambos grupos coincidieron en la necesidad de una evaluación metabólica. Para los cálculos ureterales distales ≥6 mm, los cirujanos preferían una ureteroscopía; los pediatras, una litotricia por ondas de choque (LOC) (p < 0,001); y los subespecialistas, una ureteroscopía (p = 0,636). Para los cálculos en la parte inferior de los cálices renales < 1 cm, los cirujanos y los subespecialistas preferían la LOC y los pediatras, la hidratación (p < 0,001; p = 0,371). Para los cálculos de entre 1,1 cm y 2 cm, los cirujanos preferían la cirugía retrógrada intrarrenal (CRIR) y la LOC, y los pediatras, la LOC (p = 0,001). Para los cálculos más grandes, los cirujanos y subespecialistas preferían la nefrolitotomía percutánea (NLP) y los pediatras, la LOC (p = 0,458; p = 0,001).Conclusión. Existen diferencias entre las disciplinas que participan activamente en el diagnóstico y tratamiento de la nefrolitiasis

Introduction. Pediatricians, surgeons and subspecialties as pediatric urology and nephrology are involved in the diagnosis and treatment of pediatric renal stone disease (RSD). The aim of this study was to determine diagnostic and treatment approaches, of different disciplines, and to assess differences in their routine diagnostic and treatment protocols.Population and methods. A questionnaire was designed and administered to the participants of the RSD sessions in national congresses of all disciplines in 2017 to evaluate the diagnostic and treatment routines of specialties (surgeons and pediatricians) and subspecialties (pediatric nephrologists and pediatric urologists) for RSD. Results. A total, of 324 questionnaires were analyzed, from 88 pediatricians (27 %), 121 urologists (37 %), 23 pediatric surgeons (7 %), 54 pediatric nephrologists (17 %), and 38 pediatric urologists (12 %). Both groups agreed on the necessity of metabolic evaluation. For distal ureter stones that were ≥ 6 mm; surgeons preferred ureteroscopy (URS), pediatricians preferred shock wave lithotripsy (SWL) (p < 0.001) and subspecialties preferred URS for the treatment (p = 0.636). For lower calix stones less than 1 cm surgeons and subspecialists preferred SWL, while pediatricians preferred hydration (p < 0.001, p = 0.371). For the stone between 1.1 and 2 cm, surgeons preferred intrarenal surgery (RIRS) and SWL, pediatricians preferred SWL (p = 0.001). For larger stones, surgeons and subspecialists preferred percutaneous nephrolithotomy (PCNL), and pediatricians preferred SWL (p = 0.458 p = 0.001). Pediatric urologist chose low-dose computerized tomography as a diagnostic radiologic evaluation (p = 0.029).Conclusion. There are differences between the disciplines who take an active role in diagnosis and treatment of RSD.

Voiding dysfunction due to multiple sclerosis: a large scale retrospective analysis

PURPOSE: To assess the outcome of urologic evaluation in patients with voiding dysfunction due to multiple sclerosis (MS) and to determine the relationship between urological and neurological parameters of these patients. MATERIAL AND METHODS: We retrospectively reviewed the medical records of 249 consecutive patients (162 female and 87 male) with MS who were referred to our clinic between 1991 and 2006, with a median time of 4 years (range 3 months to 26 years) of MS onset. Data was analyzed with respect to patient demographics and findings of initial evaluation. Lower urinary tract symptoms were evaluated by Boyarsky symptom index. RESULTS: All patients except 13 had lower urinary tract symptoms and 70 percent manifested mixed symptoms. Total, storage and voiding symptom scores correlated with expanded disability status scale scores (p < 0.05). Twelve patients (5 percent) had abnormal upper urinary tract. Ultrasound findings of lower urinary tract were abnormal in 12 patients (5 percent). No demographic parameters were associated with abnormal findings of upper urinary tract on univariate analysis. Urodynamic evaluation of 75 patients (30.1 percent) revealed detrusor overactivity with or without detrusor-sphincter dyssynergia in 56 (75 percent). No correlation was found between urodynamic diagnosis and upper tract deterioration and urinary symptom scores (p > 0.05). CONCLUSIONS: The prevalence of mixed symptoms in patients with MS is higher than storage or voiding symptoms alone. Although detrusor overactivity and detrusor-sphincter dyssynergia were the most common urodynamic diagnoses, upper urinary tract deterioration was rare in our series.

Does vaginal anti-incontinence surgery affect sexual satisfaction? A comparison of TVT and Burch-colposuspension

OBJECTIVE: To evaluate the sexual satisfaction rates of women who underwent tension-free vaginal tape (TVT) procedure for stress urinary incontinence and compare it with the results of Burch-colposuspension. MATERIALS AND METHODS: A self-administered questionnaire was given to 81 patients who had undergone TVT or Burch-colposuspension at our institution to determine sexual satisfaction rates and reasons for dissatisfaction. Forty-seven patients in TVT group and 22 patients in Burch-colposuspension group were considered eligible for the study. The mean follow-up period and age of patients in TVT and Burch-colposuspension groups were 34 months, 51.5 years and 89 months, 52.9 years, respectively. The difference between the ages in the two groups was not statistically significant, while the difference between mean follow-up periods was significant (p = 0.000). RESULTS: When evaluating sexual satisfaction, 73 percent in the TVT group and 86 percent in the Burch-colposuspension group did not report any difference in sexual satisfaction following surgery, while in the TVT group, 23 percent expressed negative and 4 percent positive changes, and in the Burch-colposuspension group 9 percent expressed negative and 5 percent positive post surgical changes. The differences in sexual satisfaction rates between the two groups were not considered significant. The majority (54 percent) of those who expressed a negative change suffered from dyspareunia. CONCLUSIONS: Although sexual satisfaction seems to be more adversely affected by TVT compared to Burch-colposuspension, the difference was not statistically significant. Further studies are required concerning different anti-incontinence techniques in order to arrive at more precise conclusions.
