ObjectivesTo evaluate the efficacy of tamsulosin for promoting ureteric stone expulsion in children, based on the confirmed efficacy of tamsulosin as a medical expulsive therapy in adults.Patients and methodsFrom February 2010 to July 2013, 67 children presenting with a distal ureteric stone of <1 cm as assessed on unenhanced computed tomography were included in the study. The patients were randomised into two groups, with group 1 (33 patients) receiving tamsulosin 0.4 mg and ibuprofen, and group 2 (34) receiving ibuprofen only. They were followed up for 4 weeks. Endoscopic intervention was indicated for patients with uncontrolled pain, recurrent urinary tract infection, hypersensitivity to tamsulosin and failure of stone passage after 4 weeks of conservative treatment.ResultsSixty-three patients completed the study. There were no statistically significant differences between the groups in patient age, body weight and stone size, the mean (SD) of which was 6.52 (1.8) mm in group 1 vs. 6.47 (1.79) mm in group 2 (P = 0.9). The mean (SD) time to stone expulsion in group 1 was 7.7 (1.9) days, vs. 18 (1.73) days in group 2 (P < 0.001). The analgesic requirement (mean number of ketorolac injections) in group 1 was significantly less than in group 2, at 0.55 (0.8) vs. 1.8 (1.6) (P < 0.001). The stone-free rate was 87% in group 1 and 63% in group 2 (P = 0.025).ConclusionsTamsulosin used as a medical expulsive therapy for children with ureteric stones is safe and effective, as it facilitates spontaneous expulsion of the stone.
Introduction and Objectives: A comparative study of standard radical cystectomy and prostate capsule sparing radical cystectomy regarding functional and oncological outcomes. Materials and Methods: A randomized study of 96 patients with transitional cell carcinoma of the bladder (December 2014 - June 2016) was done. We excluded cases with preoperative T4 staging, lymphadenopathy, prostatic specific antigen > 4 ng/dl, and cases with positive biopsies from the bladder neck, trigone, and/or prostatic urethra. Patients were divided into 2 groups, Group 1: standard radical cystectomy with orthotopic diversion (n = 51), Group 2: prostate capsule sparing cystectomy with orthotopic diversion (n = 45). Preoperative transrectal ultrasound and prostatic biopsies were done in Group 2 to exclude prostate cancer. We compared the urinary continence and erectile function in both groups after 6 months, 1, and 2 years. Results: There was no significant difference between the groups regarding preoperative demographic data, tumor stage, grade, site by cystoscopy, and biopsy. Intraoperative monitoring showed no significant differences regarding blood loss, surgical complications, or operative time (2.5 ± 0.48 vs. 2.4 ± 0.45 h). There was a significantly higher percentage of continence and potency in Group 2 than in Group 1. Sixteen cases (35.6%) in Group 2 but only 4 cases (7.8%) in Group 1 developed large post-voiding residual urine and needed intermittent self-catheterization cleaning (p = 0.001). The tumor recurrence rate was not significantly different between the groups after 2 years (p = 0.3). Conclusion: Prostate capsule sparing cystectomy is a good option in selected cases with better continence and potency and without compromising oncological outcomes after 2 years.
The scoring systems analyzed could be used to predict success of percutaneous nephrolithotomy in the pediatric setting. However, further studies are needed to formulate modifications for use in children. The main variables in the scoring systems, ie stone burden, tract length and case volume, were measured using records from adult patients. Besides these variables, the relatively small pelvicalyceal system and higher incidence of anatomical malformations in children could potentially affect percutaneous nephrolithotomy outcomes.
Venous blood samples were taken from eight competitors in mid-evening after a racing day, and in the early morning before the next day's race, three times during the course of the Milk Race, 1992. These were used to gather information about the changes in circulating leucocyte levels in response to the exceptionally high sustained daily workload required during a major multi-stage race. The primary objective was to provide knowledge of 'normal' values against which future clinical judgements of abnormality might be made in these unusual circumstances. During the race, estimated energy output was about 25 MJ (6000 kCal)/day. The mean total circulating leucocyte numbers (per litre of blood), and those of individual leucocyte classes (neutrophil, lymphocyte, monocyte, eosinophil and basophil) were all inside the normal range both in the morning and in the evening. Evening counts were, however, 30-50% higher than morning counts, for all classes except eosinophils. We conclude that individual clinical decisions about leucocyte levels can best be made using normal (sedentary man) values if a morning sample is taken.Keywords: heavy exercise, leucocytosis, cycling, circadian This brief study was initiated after reading a newspaper report that a competitor in the 1991 Tour de France had been advised to retire from competition because 'Doctors had found a high white cell count' and suspected a viral infection. No more information than this was given, but it raised the question in our minds 'What is high in the context of the Tour de France?' What standards of normality were applied? Exercise is well-known to induce a substantial leucocytosis, and this may be both transient and delayed, the latter being relatively persistent, even when induced by a limited period of severe exercise'. We decided that it would be useful to seek normal values in the unusual context of a major cycle stage race, by sampling in the two periods when it seems most probable that a competitor might present himself to a doctor with complaints of feeling unwell; namely at the end of a day (in the mid-evening), or early in the morning, soon after waking.A delayed leucocytosis (at 3h into recovery) has been reported in response to single bouts of exercise2, or even to double bouts of exercise in the laboratory3 that is typically a pure neutrophilia, although following 3 h of exhaustive exercise, monocytosis and eosinopaenia were noted in recovery4. It has been hypothesized that the delayed peak in neutrophil leucocytes is induced by the earlier elevation in cortisol level caused by the exercise. It is well-known that cycle stage races involve massive workloads, which have been assessed to amount to a mean energy expenditure of about 25 MJ and a maximum of about 32.5 MJ/day (6000 and 7800 kCal/day respectively) during the Tour de France5. It is also known that cortisol turnover is normally related to energy turnover during exercise6. Such high levels of work are therefore bound to involve relatively high cortisol outputs, which might be expected to exert...
