Abstract Our results were obtained by examining subjects without renal pathology, aged 26-83 on a General Electric - Voluson 730 Expert ultrasound. The left kidney length was found between 56.98-122.90 mm, for female being 56.98-110.60 mm, and for male 84.73-122.90 mm. The length of the right kidney was between 55.50-125.0 mm, for female being 55.50-108.40 mm, and for male 62.04-125.0 mm. The width of the left kidney in the renal hillum was found to be between 15.54-41.10 mm, for female being between 15.54-31.0 mm, and for male between 16.19-41.10 mm. The thickness of the left kidney in the renal hillum was found to be between 40.0-75.80 mm, with the female being 44.02-71.02 mm, and the male between 40.0-75.80 mm. The right kidney thickness in the renal hillum was found to be between 41.67-82.36 mm, for female being between 41.67-60.27 mm and for male 43.89-82.36 mm.

Introduction: Ultrasound is an important imaging modality used in the prognosis and diagnosis of renal conditions and diseases and also in the evaluation of kidney donors. This study aimed at providing a reference for the normal metric variables of the kidney such kidney lengths of healthy Nigerian adults in Lagos State and to compare with previously obtained results.Materials and Methods: This study was conducted in the radiology department of Ikorodu Hospital. This study adopted a descriptive cross-sectional study design with a cluster sampling approach which consisted of 150 adults (with 300 kidneys) participants ages 18-87 years. Real-time gray-scale ultrasonic scanning using Prosound 3500 Aloka device and a 3.5–5 MHz curvilinear explorer was employed for the abdominal imaging. The data acquired were compiled and explored via the Statistical Package for the Social Sciences (SPSS) version 20. The student’s t-test was utilized in probing for statistical significance between age as well as gender in relation to renal length. P-value < 0.05 was adjudged to be significant.Results: The kidney length was of a greater distance in males, and the length of the left kidney was more extensive than that of the right kidney in both sexes. Average kidney length was greater on the left when compared to the right among the various age groups. No significant association was noted between kidney length and age as well as gender.Conclusions: Normal values for kidney length and diversifications in the kidney length of healthy adults in Nigeria have been established.

Renal Length

Introduction. Malformations in kidney development and kidney diseases are accompanied with changes in their size. For kidney evaluation in clinical practice, the kidney length is the most widely used measurement, since it provides the most precise results and it is easy to perform. Recently, the measurement of relative renal length has become more preferable as it takes into account the body height. The aim of this study was to measure both the absolute and relative length of normal cadaveric kidneys according to the body height, sex and age. Material and methods. In this study, we examined 95 adult cadaveric kidneys, without renal and vascular impairment, their age ranging from 23-87 years. To determine the period of the most abundant changes in kidney length, we separated them into a 10-year range. The relative renal length was calculated using the kidney length anybody height ratio (kidney/body ratio). Results. The absolute and relative length of left kidney in males was longer than the right one, with a statistically significant correlation. In females, the left kidney length was also longer than the right one, however, without a statistical significance. In contrast to the absolute length, the relative length of both kidneys did not show a significant difference between sexes, and did not manifest a significant decrease with age. There was a significant correlation between the kidney length and the subject?s height. Conclusion. The relative renal length represents kidney size better than the absolute renal length because it eliminates sex and height differences until the age of 59 year. From the seventh decade of life, there is a significant decrease in both the absolute and relative renal length.

The kidneys are bilaterally paired organs and serve several essential functions required to maintain a normal human physiological function. The renal size was conventionally determined on x-ray or urography by measuring the renal length distance of first lumbar vertebrae to third or fourth lumbar vertebrae. Ectopic position of the kidney can be associated with ureteric stone, vesicoureteric reflux and can predispose to iatrogenic trauma during interventional radiological and laparoscopic procedures and any surgeries. Therefore, it is important to know the variations between individuals in the level of kidney relative to the spinal column. The study aimed to analyse the morphometric and morphologic measurements of the kidney using CT angiogram in kidney donors. In this study, the length and breadth of kidney and different level of location of kidney in 100 renal donors were analysed. The study was conducted in specialised scan centres located in Chennai. Out of 100 kidney donors, 61% of them were male & 39% of them were female. The right kidney length was found to be 10.59 ±1.14 cms, and left kidney length was found to be 10.72 ± 1.22 cms. This report will be useful for transplant surgeries, as well as clinicians and radiologist who perform various techniques.

Abstract We present an interesting case of a 70-year-old female who presented with haematuria on the suspected cancer pathway. Renal ultrasound showed a vascular renal mass on her right kidney measuring 8x7cm with an unremarkable left kidney. She underwent a laparoscopic radical nephrectomy following confirmation of an 8cm renal mass in the right kidney on the contrasted staging CT scan with a repeat review at the multidisciplinary meeting. Post-operatively a subsequent review of the pre-operative CT and ultrasound scan, showed an incidental large left(contralateral) upper quadrant retroperitoneal fatty mass sized 15x10cm, displacing the stomach and spleen. Further investigation in the form of an MRI Abdomen excluded features of a liposarcoma, resulting in the diagnosis of a large retroperitoneal lipoma. This case highlights the significance of selective attention in imaging interpretation. We believe this to be a prime example of the level of meticulousness required as fat-rich tissues have low attenuation on CT-scans, which can be easily missed out. A cautious multi-clinician interpretation of scans should be performed to avoid missing potentially sinister pathology which would impact patient care dramatically. This case has led to more thorough review of future pre-operative imaging by the operating surgical team.

The use of kidney grafts with aneurysmal disease involving the renal arteries for transplantation is very uncommon and relatively controversial. We herein present the case of a 52-year-old woman who volunteered to become a living-nonrelated donor; during the preoperative imaging workup, a computed tomography angiography revealed a 1.5-cm saccular aneurysm in the left kidney, while the contralateral renal artery was normal. We decided to utilize the left kidney for a 25-year-old male patient with end-stage renal disease, and following the ex vivo repair using the recipient epigastric vessels and saphenous veins, we completed the transplantation in the right pelvic fossa. The postoperative period was uneventful, and at 8 months from the surgery, the graft remains functional. The surgical repair of renal artery aneurysms followed by immediate kidney transplantation is a safe technique and an effective replacement therapy for recipients. The incidental finding of isolated aneurysmal disease in renal arteries should not exclude graft potential availability for transplantation following repair.

Abstract Background Pediatric hydronephrosis induced by pelvic-ureteric junction obstruction (PUJO) is treated by dismembered pyeloplasty (DP) via open and laparoscopic surgery. The etiology of PUJO involves both intrinsic stenosis and extrinsic compression of crossing vessels (CVs). PUJO owing to CVs is also treated by DP, as there is no consensus concerning this vascular condition. We encountered a 2-year-old infant with pure extrinsic PUJO combined with horseshoe kidney who successfully underwent laparoscopic transposition for CVs (vascular hitch). Case presentation A 2-year-old boy was prenatally diagnosed with left multicystic dysplastic kidney (MDCK) and right hydronephrosis and received a definitive diagnosis after birth. At 6 months old, renal scintigraphy revealed a non-functioning pattern in the left kidney and an obstructive pattern in the right, showing no response to furosemide loading. The patient also had recurrent urinary tract infection, and his right hydronephrosis gradually worsened. We decided to perform surgery for the right PUJO. Preoperative enhanced computed tomography detected three right renal vessels independently branching from the abdominal aorta. The middle renal vessels were located at the ventral side of the pelvis and coincident with the site of PUJO. These vessels were suspected of being CVs. The patient underwent laparoscopic surgery electively. A 5-mm trocar was inserted at the umbilicus for a 5-mm, 30° rigid scope. Two additional ports were then inserted under laparoscope inspection. The dilated right pelvis and CVs were detected after ascending colon mobilization. To confirm the pathogenesis of PUJO, the CVs were dissected and taped. After taping the CVs, an intraoperative diuretic test was performed using furosemide loading. Peristalsis of the right ureter was recognized, and the extrinsic PUJO owing to the CVs was definitively confirmed. We therefore performed transposition for the CVs (vascular hitch procedure). The CVs were mobilized in the cranial direction and those were wrapped by dilated pelvis. The post-operative course was uneventful. The renal scintigraphy findings improved and showed a favorable response of furosemide loading. Conclusions The laparoscopic vascular hitch procedure is minimally invasive and effective for extrinsic PUJO due to CVs. Anastomotic stricture after Anderson and Hynes DP can be prevented by appropriate patient selection.

A stone is not only an obstacle, sometimes painful, on the urinary tract justifying an emergency urological gesture to restore their permeability. It is primarily a symptom of crystallogenic pathologies or urinary imbalances of nu-tritional origin whose recurrence is the rule if the cause has not been correctly identified. It is therefore recommended in the patient's interest; analyze the calcul or its fragments to determine its composition and structure, one and / or the other orienting towards the pathology in question. A series of 166 urinary stones were collected nearby the hospitals of western Algeria after urological intervention or spontaneous expulsion and sequential analysis of the nucleus at the surface by Fourier transform infrared spectrophotometry. The male / female ratio was 1.78. The study of the anatomical localization of the stones showed a predominance of the high urinary tract with a rate of 76.9%. 27.3% of the stones were located in the left kidney compared to 25.7% in the right kidney. Analysis of the crystalline composition showed that calcium oxalate was predominant in 65.8% of the calculs and in 58.5% of the nuclei. In all, whewellite was present in 46.9% of cases and weddellite in 18.9%. uric acid anhydrous was the major component of 12.2% of the calculations analyzed. It was present in 23.3% of cases with predominance in subjects over 60 years. Our results show that the lithiasis of the urinary tree in western Algeria tends to evolve in the same direction as that of the industri-alized countries.

A series of 12 cases of Wilms' tumor, in which the diagnosis was confirmed in all instances by examination of the gross or microscopic tissue, is reported, with a survival rate of 33.3%. Four patients are living and well, 4, 8, 10, and 15 years, respectively, after treatment. All recurrences appeared less than 10 months after treatment. The sex incidence, and the sex survival incidence were exactly equal. Six tumors were in the left kidney, and six in the right. Eight of the patients were under 2 years of age when first diagnosed and treated, and all were under 7 years. The history of breast or bottle feeding was irrelevant. In a large number of these and reported cases, the presence of the tumor was the first symptom, and in a considerable number the only symptom. This fact stresses the importance of careful physical examination of infants and young children, regardless of complaint, or of lack of it. The finding of calcification in the tumor is possibly a good prognostic sign. All three patients in whom calcification was noted in the tumor are living and well. Immediate removal of the tumor by transperitoneal nephrectomy, with postoperative radiation to the area, seems to be the advisable treatment.

Acute left renal denervation in anesthetized volume-expanded rats produced an ipsilateral diuresis and natriuresis in 19 animals. A simultaneous decrease of glomerular filtration rate, p-aminohippurate clearance, urinary volume (P < 0.002), and percentage of filtered sodium excreted (4.0 +/- 0.6 (SE) vs. 1.9 +/- 0.4%, P < 0.003) occurred in the right innervated kidney in 10 rats. Prior denervation of the right kidney in the other nine rats prevented the renal hemodynamic changes and the fall of urinary volume and of sodium excretion (3.9 +/- 0.6 vs. 4.3 +/- 0.5%) by the right kidney after left renal denervation. Nerve traffic to the right kidney was measured in six other animals after left renal denervation and was found to increase to a mean value 33.8 +/- 6.3% above control levels (P < 0.007) 0-30 min after denervation, with a further significant increase to 66.2 +/- 16.1% above control levels (P < 0.025) 30-60 min after denervation. These results indicate that the functional changes in the right kidney after contralateral renal denervation in volume-expanded rats are caused by a reflex increase in nerve traffic to the right kidney, possibly as a consequence of an interruption of afferent nerve activity originating in the left kidney.
