Longitud renal y aclaramiento de la creatinina en pacientes embarazadas con enfermedad renal crónica / Renal length and creatinine clearance in pregnant patients with chronic kidney disease

Resumen: OBJETIVO: Medir, con ultrasonido, la longitud renal y el aclaramiento de creatinina para evaluar su correlación en pacientes embarazadas con enfermedad renal crónica. MATERIALES Y MÉTODOS: Estudio transversal, analítico y retrospectivo efectuado en pacientes embarazadas con enfermedad renal crónica a quienes se midió, con ultrasonido, la longitud renal derecha, izquierda, total y el aclaramiento de creatinina calculado con la ecuación Modification of Diet in Renal Disease (MDRD) para evaluar su correlación como grupo y por trimestres del embarazo. Se utilizó estadística descriptiva, prueba de ANOVA de una vía y el coeficiente de correlación de Pearson (r) con el programa estadístico SPSS versión 20. Los valores p < 0.05 y r > 0.1 se consideraron significativos. RESULTADOS: Se estudiaron 50 pacientes. La longitud renal derecha fue 75.52 ± 16.14 mm, izquierda 84.46 ± 16.51 mm y total 159.96 ± 28.59 mm. La media del aclaramiento de creatinina fue 34.17 ± 25.63 mL/min/1.73 m2 área de superficie corporal. La correlación resultó positiva para la longitud renal izquierda vs aclaramiento de creatinina (r = 0.362) y longitud renal total vs aclaramiento de creatinina (r = 0.346) con mayor evidencia en pacientes en el segundo trimestre del embarazo. Las pacientes en el primer trimestre del embarazo fueron de mayor edad (p = 0.004), con riñones más pequeños (p = 0.008), menor aclaramiento de creatinina (p = 0.001) y mayor frecuencia de enfermedad renal crónica terminal (18%). CONCLUSIONES: Se encontró incremento de la longitud renal izquierda, longitud renal total y aclaramiento de creatinina con correlación positiva. Los cambios fueron evidentes solo en pacientes en el segundo trimestre del embarazo.

Abstract OBJECTIVE: To measure renal length by ultrasound and creatinine clearance to assess its correlation in pregnant patients with chronic kidney disease (CKD). MATERIALS AND METHODS: Cross-sectional, analytical and retrospective study in pregnant patients with CKD whose right, left and total renal length was measured by ultrasound and the creatinine clearance calculated with the Modification of Diet in Renal Disease (MDRD) equation to evaluate its correlation. as a group and by gestational trimesters. Descriptive statistics, one-way ANOVA test and Pearson's correlation coefficient (r) were used with the SPSS version 20 statistical program. The p < 0.05 and r > 0.1 value was considered significant, respectively. RESULTS: 50 patients were studied. The right renal length was 75.52 ± 16.14 mm, left 84.46 ± 16.51 mm and total 159.96 ± 28.59 mm. The mean creatinine clearance was 34.17 ± 25.63 mL/min/1.73 m2 body surface area. The correlation was positive for the left renal length vs creatinine clearance (r = 0.362) and total renal length vs creatinine clearance (r = 0.346) with more evidence in second trimester patients. The first trimester patients were older (p = 0.004), smaller kidneys (p = 0.008), reduced creatinine clearance (p = 0.001) and higher frequency of terminal chronic kidney disease (18%). CONCLUSIONS: An increase in left kidney length, total kidney length and ACr was found, whose correlation was positive. The changes were evident in second trimester pregnant patients.

Measurements of the normal size of spleen and spleen to left kidney ratio among sudanese children up to five years age using ultrasonography

Background: Knowledge of the normal range of spleen size in the population being examined is very important because there are many different pathological conditions that may alter in spleen size. Also, gender, height, weight and BMI of individual, affect the splenic length and could result in incorrect interpretation of splenic measurements, spleen to left kidney ratio is one of recent parameter mention in literature aid in diagnosis of splenomegaly in children.Methods: The study was a cross-sectional study conducted in Khartoum state at Al-Buluk and Gaafar Ibnauf Paediatric Tertiary Hospital during the period from March 2018 to August 2018. A total of 101 children (males and females) with aged ranged 1 month to 5 years included in study. A transabdominal scan was performed, and measurement of spleen and left kidney taken after an ethical verbal consent from their parents, then data analyzed by SPSS, Mean±SD. Deviation for study variables calculated then correlation between patients factors and ultrasound measurements done.Results: The study found that the mean measurements of the normal size of the spleen and spleen to left kidney ratio for children up to five years of age, Splenic length was 7.24±1.12 cm, width was 3.83±0.81 cm , thickness 2.91±0.55 cm and spleen to left kidney ratio was 1.04±0.0.70 ranged (0.86-1.23). The male have larger spleen than female with no statistically significant differences in spleen sizes between the sexes. There was a strong significant correlation between age, weight, height  spleen and left kidney length (p<0.01)respectively and a moderate association with BMI (p<0.05).Conclusions: Spleen and left kidneys was growing rapidly and similarly in infant up to one year of life 1 mm\1 mm for each month and then decreasing growth rate of kidney in relate to spleen for 1 mm growth of spleen kidney grow 0.8 mm in up to five years of age. There was strong significant positive correlation between spleen and left kidney measurement with age, height, weight of individual. The spleen to left kidney ratio for children up to five years ranged (0.86-1.23) with mean 1.04, so if the ratio less or more than this ranged it should be considered in clinical context for diagnosis of splenomegaly or shrunken spleen in children up to five years of age.

Non-classical congenital adrenal Hyperplasia with accompanying congenital anomalies: Vaginal atresia, left kidney agenesis, and urogenital malformations

@#A 16-year-old male-looking patient presented at the emergency room for severe abdominal pain. Physical examination revealed acute abdomen, ambiguous genitalia, empty rectal vault with watery discharge and right lower quadrant palpable mass. Ultrasound showed a uterus and right adnexal mass. General surgery evaluated urethral patency and noted presence of recto-urethral fistula. Surgical exploration, right salpingo-oophorectomy and suprapubic cystostomy were done. Immediate referral to a reproductive endocrinologist was done postoperatively. Retrograde urethrogram and cystogram revealed neurogenic bladder with fistula formation. On follow up, whole abdomen MRI revealed thickened endometrium with fluid levels, tortuous left fallopian tube, multiloculated left adnexal mass and left renal agenesis. Serum levels of 17-hydroxyprogesterone and cortisol were noted to be elevated and karyotyping revealed 46 XX. Patient then underwent psychiatric evaluation and assessment. Patient was readmitted for urology and pediatric surgery diagnostic work up. However, regardless of the findings, patient decided not to undergo further surgeries and opted to be female.

Correlation of volume of both the kidneys in both the sexes among different age groups of normal North Indian population – An ultrasonographic study.

Background: Dimensions of kidney form an extremly important parameter for diagnosis and prognosis of renal pathologies. Dimensions vary according to the geographical locations, racial variations, diet, environment and frequency of pathologies. Renal sizes in Indian population although studied frequently have not been standardized. Aim: The study was aimed at establishing Aim: The study was aimed at establishing some preliminary data of normal North Indian population, without a known renal pathology. Material and methods: Renal measurements i.e., length, width and parenchymal thickness were measured in 164 individuals, both males and females and their renal volume was calculated. The volume was then correlated with the age of the individuals. Analysis was then done for variability due to age, gender and laterality. Results: It was found that the males showed the maximum volume for both the right and the left kidneys in the fourth decade, where as the females had a maximum volume in the third decade. Volume tended to decrease after the fourth decade. The volume of the left kidney was more as compared to that of right side for both the males and females. Conclusion: Renal sizes of Indian are invariably lesser as compared to commonly quoted normal values in standard literatures. Inferences about renal sizes need to be made with reference to racial and regional variations rather than basing them on data from other population.
