Uroflowmetric analysis and derivation of nomograms for normal paediatric Indian population between 5 to 15 years of age.

Objective: We aimed to established normal uroflowmetric values and subsequently derived nomograms of maximum flow rate (Qmax) and average flow rate (Qavg) against voided volume (VV) in children aged 5-15 years at our institute. Methods: A total of 440 children underwent uroflowmetric evaluation with no history of urological, renal, psychiatric, or neurological disorder between 5 and 15 years of age. Each subject data regarding Qmax, Qavg, VV, time to Qmax, and flow time, as well as age, sex, height, and weight were recorded. Of the 440 children, around 300 (68.18%) children could produce a normal flow rate at VV of more than 50 mL. Of the remaining 140 (31.82%) children, 50.00% voided less than 50 mL, and remaining 50.00% had abnormal voiding pattern, staccato or interrupted (21.43% each) and plateau or tower shaped (3.57% each). Cases were divided into two age groups (5-9 years and 10-15 years), and uroflowmetric analysis was done between boys and girls in both age groups to derive nomograms of Qavg and Qmax. Results: Qmax and Qavg flow nomograms were plotted for boys and girls. Mean Qmax for boys was 16.68 mL/s and for girls 20.69 mL/s. The mean Qavg values were 11.04 mL/s and 8.60 mL/s for girls and boys, respectively. The Qmax and Qavg values were higher in girls. There were significant increases in flow rates with increasing age, body surface area, and VV in both sexes. Conclusions: Nomograms for Qmax and Qavg may be a useful tool in evaluation of lower urinary tract disturbances in children.

Survey of semen analysis practices in India and need for standardization and improvement.

BACKGROUND AND OBJECTIVES: Infertility is a sensitive subject carrying with it economic, social, and psychological implications. Work up of male infertility is often hampered by a lack of infrastructure and facilities, as well as inadequate training of pathology residents. The purpose of this research survey was to evaluate the current status of semen analysis practices and compare them to the standards laid down by the World Health Organization (WHO). MATERIALS AND METHODS: A web-based questionnaire was designed consisting of questions related to semen analysis practices and procedures being followed currently by pathologists in India. A total of 194 pathologists responded. Questions regarding the procedures followed for semen collection, sperm count, volume, normal range, lower normal limit of sperm count, morphology, etc., were included in the survey. These data were recorded. The differences and gaps in the practice with respect to the WHO standards were analyzed. RESULTS: The survey revealed that the printed instructions for semen analysis were available with 38.7% of the respondents; 58.8% of the respondents had a separate room for semen collection; 95.9% performed the analysis manually, and; only 4.1% used automated analyzers. Only 53.6 and 52.6% of the respondents were correctly reporting the normal range of semen volume and sperm counts, respectively. Only 19.6% stated as having read the WHO manual and were also practicing its guidelines, while 14.4% had not read the WHO manual even once. CONCLUSION: The present study showed a large gap between the practice of semen analysis by respondents from various parts of India and standard procedures as laid down by the WHO. Many laboratories do not follow the standard instructions. There is a need to improve the quality of practice related to semen analysis in this country through appropriate teaching and training in medical institutions as well as through Continuing Medical Education (CMEs) or regular update programs.

Retrospective Analysis of the Comparison Between Single Renal Artery Versus Multiple Renal Arteries in Living Donor Kidney Transplant: Does It Affect the Outcome?

OBJECTIVES: There is an increased risk of vascular complications in kidney transplant for allografts with multiple renal arteries versus a single renal artery. We compared the clinical outcomes of living donor kidney transplant recipients who received allografts with a single renal artery versus multiple renal arteries. MATERIALS AND METHODS: This retrospective analysis included all living-related donor kidney transplants that were performed by a single skilled urologist. All donor nephrectomies were performed by open method. The left kidney was preferred over the right for donor nephrectomy, except in cases of vascular problems or other contraindications, for which the right kidney was preferred. In most of the cases, kidneys were placed in the right iliac fossa for transplant by an extraperitoneal approach. RESULTS: Of 97 living donor kidney transplants, 82 had a single renal artery (group 1) and 15 had multiple renal arteries (group 2). Patients ranged in age from 18 to 76 years old. Recipient ages (33.00 vs 29.46 years) and baseline serum creatinine values (8.61 vs 8.82 mg/dL) were comparable in groups 1 and 2 (P > .05). However, mean operative time and total ischemia time were significantly higher in the multiple renal artery group (221 and 53.45 minutes, respectively) compared with the single renal artery group (202 and 77.6 minutes, respectively). Graft survival at 1 year was 95.12% in the single renal artery group and 93.33% in the multiple renal artery group. Patient survival at 1 year was 96.34% in the single renal artery group and 93.33% in the multiple renal artery group. CONCLUSIONS: The safety of kidney transplants of allografts with multiple renal arteries is equal to the safety of transplants of allografts with a single renal artery in terms of vascular complications and acute tubular necrosis, as well as patient and graft survival.
