Bilateral nephroureteral stents are present and can be perceived faintly on the excretory phase image. Note also the right renal cysts and a small filling defect in a left lower pole calyx; this was a small calculus....

A 57-year-old female patient underwent left breast-conserving surgery with sentinel lymph node biopsy for Left breast carcinoma (stage IIA). The patient had hypertension and diabetes mellitus. Other findings include multiple hepatic cyst, bilateral renal cysts and uterine myoma. She had no significant renal symptoms and her liver &renal function test were normal.She was sent for Technetium-99m-methylene diphosphonate (99mTc-MDP) bone scan. There was a large area of intense tracer concentration in the region of right sacro-iliac (SI) joint which appeared like an osteoblastic metastasis at first glance. However, absence of uptake in the right renal fossa with the left kidney being normal in position contemplated the probability of right-sidedpelvickidneywhich was confirmed later by a contrast enhanced computerized tomography (CT) scan of abdomen that showed a pelvic right kidney overlying the sacrum.

68-year-old woman with microhematuria Coronal oblique arterial phase 3D SPGR images from MR urography (Figure 8.25.1) demonstrate soft tissue thickening surrounding the renal pelvis and proximal ureter, with mild hydronephrosis and hydroureter. Periureteral lymphoma Involvement of the GU system by non-Hodgkin lymphoma is not infrequent, and the kidneys are most often affected. Ureteral lymphoma generally occurs as a result of contiguous spread from adjacent retroperitoneal nodes or from the kidney. This case is unusual in that ureteral involvement was the primary manifestation of the disease....

ABSTRACT A 6 mo old 13.5 kg (29.7 lb) male intact American Staffordshire terrier was evaluated for a history of supernumerary pelvic limbs, with malodorous discharge from a supernumerary penis. Imaging (radiographs, abdominal ultrasound, and computed tomography with excretory urogram) showed a supernumerary pelvis with associated pelvic limbs, no osseous continuity with the primary spinal column, a colonic diverticulum extending to the supernumerary pelvis, an enlarged left kidney with a ureter connecting to a single bladder, right renal aplasia, a single descended testicle in the primary scrotum, an intra-abdominal cryptorchid testicle, and two unidentifiable soft tissue masses. At surgery, a single ileum was present with a primary and accessory cecum and colon and the accessory colon entering the supernumerary pelvis. The accessory cecum and colon, right kidney, two unknown soft tissue masses, and the single descended testicle were removed. The right kidney had a ureter that anastomosed with the accessory colon at its entry into the supernumerary pelvis. The supernumerary pelvis and hind limbs were not removed. Five months after surgery, the dog was reported to be doing well clinically. Caudal duplication is extremely rare in veterinary medicine. The appearance of supernumerary external structures may indicate internal connections as well.

Left Inguinal Region

Undescended testis is one of the most common congenital anomalies in newborns. Incidence of this is anywhere between 1.6% and 9.0%. The incidence dramatically drops to 0.9-1.8% at 3 months of age. This is due to the spontaneous descent of the testes. The complications of undescended testes are infertility and malignant transformation. A 29-year-old unmarried male patient came to the hospital with complained of absent of left testis within scrotal sac since birth and a left inguinal swelling since 1 year with no other complaints. On examination, the left scrotal sac was empty. The right side scrotum was normal and testis was palpable within scrotal sac. On USG, examination findings were confirmed Left testis seen in relation to lower pole of left kidney in left inguinal region with normal echo texture s/o left ectopic testis. Left kidney in pelvic region at paramedian location with hilum facing anteromedially s/o left ectopic kidney. Early diagnosis and surgical intervention is key so as to preserve the undescended testis and prevent malignant change or infertility problems. It is imperative that all tests be done to assess kidney function.

Multiple Cysts

Cystic renal disease is rare in dogs and although infected renal cysts have been reported in humans, no report could be found in dogs. A 58 kg, 5-year-old, castrated, male Boerboel presented with weight loss, pyrexia, lethargy and vomiting, 20 months after an incident of haematuria was reported. The initial ultrasonographic diagnosis was bilateral multiple renal cysts of unknown aetiology. The cysts had significantly increased in size over the 20-month period and some contained echogenic specks which could be related to infection, normal cellular debris or haemorrhage. In both kidneys the renal contours were distorted (the left more than the right). The abnormal shape of the left kidney was largely due to multiple cysts and a large crescent-shaped septate mass on the cranial pole of the kidney. Aspirates of the septate mass were performed (left kidney) and the cytology and culture were indicative of an abscess. It is suggested that the previous incident of haematuria provided a portal of entry for bacteria into the cysts resulting in renal cortical abscess formation.

Renal Neoplasia

A 13-year-old, spayed, female Australian Cattle Dog had at least a 10-year history of numerous subcutaneous nodules for which fine-needle aspiration and cytologic evaluation were nondiagnostic. Abdominal ultrasound 3.5 months before necropsy detected a small left kidney but no cysts or neoplasms. At gross necropsy, innumerable, firm, round to oval, white, 0.25 to 2 cm masses were detected throughout the subcutaneous tissues of the axial and appendicular skeleton, epimysium of numerous muscles, and parietal peritoneum of the lateral abdominal body wall. The left kidney was approximately half the size of the right, and there was severe bilateral renal medullary (papillary) necrosis. Histologically, the subcutaneous nodules were well-demarcated masses of mature, hypocellular collagen that were consistent with previous reports of nodular dermatofibrosis and renal cystadenomas or cystadenocarcinomas. In addition to diffuse acute medullary necrosis, both kidneys were affected by severe chronic lymphoplasmacytic interstitial nephritis. This is the first known report of nodular dermatofibrosis in a dog without renal cysts, cystadenoma, or cystadenocarcinoma.
