ABSTRACT Retrocaval ureter (RU) is an abnormal embryonic development of the caudal vena cava (CVC) that leads the ureter to be entrapped dorsal to the CVC. In most cases there is no clinical impact; however, it can cause hydronephrosis. We report a rare case of type II symptomatic retrocaval ureter in a feline treated with nephroureterectomy. A 4-year-old, intact male, mixed breed cat was submitted to abdominal ultrasound and severe right hydronephrosis was diagnosed, with no signs of obstruction. We performed an exploratory celiotomy, in which a displacement of the right ureter dorsal to the CVC was observed. The animal was treated with ureteronephrectomy and recovered well. No intraluminal cause was found, and a urethral catheter could be easily inserted across the ureter length. The real clinical relevance of the RU is unknown, since it is a common find in post-mortem examination without kidney impact and, when significant, is often associated to other causes of ureteral obstructions, such as calculi and strictures. Additionally, in humans, type II RU seldom develops obstruction and hydronephrosis. In our case, due to absence of other causes of obstruction, probably mechanical compression of the CVC against the psoas muscle caused the hydronephrosis.

Background/Aim. In this paper, we analyzed type I and type II muscle fibers of the iliopsoas muscle in persons of both genders with ageing. The aim of this study was to detect the presence and distribution of types I and II muscle fibers in the human psoas muscle using the hematoxylin and eosin method in individuals of different ages and genders. Methods. The material consisted of tissue samples of the right iliopsoas muscle taken from 30 adult cadavers (18 males and 12 females), aged from 30 to 90 years, divided into three age groups. The material was obtained from the Institute of Forensic Medicine, Faculty of Medicine University of Nis. Results. The values of astereological parameters (area, perimeter and Feret's diameter) of type I and type II muscle fibers were higher in male cases, although without any statistical significance. Conclusion. Based on the histochemical and morphometric analysis, the conclusion was drawn that after 70 years of life there occurred a loss of type II muscle fibers, more conspicuous in female cases.

ABSTRACT An 8 mo old intact male mixed-breed dog presented for diphallia with paraphimosis of the nonfunctional, accessory penis. Bloodwork, an abdominal ultrasound, and a positive contrast retrograde urethrogram were performed and revealed no other structural abnormalities. Surgical excision of the accessory penis was elected. This is one of three reported cases of diphallia in the dog in the English literature, but this is the only case in which no other congenital abnormalities were identified. The authors also review diphallia in both the veterinary and human literature.

Abstract Background Intravascular leiomyomatosis with intracardiac extension is a rare benign tumor seen exclusively in women, characterized by proliferation of uterine smooth muscle cells through the venous circulation into the inferior vena cava and the right heart chambers. Case summary A 47 years old women with history of previous hysterectomy due to myomatosis, presented with nausea, anorexia and bilateral lower limb swelling over the preceding two months. An outpatient abdominal ultrasound discovered a mass in the Inferior vena cava. Echocardiogram and Computed tomography demonstrated a large intravascular mass extending from the pelvis to the right heart chambers. The tumor was completely removed in a concomitant open-heart surgery and laparotomy. Post operative course was uncomplicated. A month later the patient was feeling well and in good clinical condition. The histological analysis consisted with intravascular leiomyomatosis. Discussion Intracardiac leiomyomatosis is a rare clinical condition which requires high index of suspicion. Multimodality imaging is usually required to establish the preoperative diagnosis, although the final diagnosis is achieved with tissue investigation. Complete surgical resection of the tumor is curative and associated with good long-term prognosis.

Retrocaval ureter (RCU) is a rare congenital anomaly in which the ureter passes posterior to the inferior vena cava (IVC). A little over 200 cases have been reported worldwide since Hochstetter’s first report in 1893. We present two cases of retrocaval ureter which were successfully managed at the Cape Coast Teaching Hospital in Ghana. Case 1. A 55-year-old woman presented with a history of dull right flank pain of 2 years duration. Physical examination and basic laboratory investigations performed on her were normal. Abdominal ultrasound showed right hydronephrosis and a retrograde right ureteropyelogram (RPG) showed right hydroureteronephrosis with an “S” shaped proximal ureter. A diagnosis of retrocaval ureter was made and confirmed at surgery. Case 2. A 25-year-old man presented with dull intermittent right flank pain of 1 year duration. Clinical examination and laboratory investigation were normal. Abdominal ultrasound showed right hydronephrosis and a CT urogram made a diagnosis of retrocaval ureter which was confirmed at surgery. Conclusion. Retrocaval ureter is a rare congenital anomaly that is now increasingly being reported. Surgical treatment of symptomatic cases successfully relieves symptoms.

ABSTRACT A 9 yr old castrated male mixed-breed dog was presented for acute vomiting. Abdominal radiographs appeared to show a normal positioned stomach with marked gas dilation, which persisted despite frequent suctioning with a nasogastric tube. An abdominal ultrasound showed splenomegaly, malpositioning of the spleen, and the pyloroduodenal junction. A ventral midline celiotomy revealed an organoaxial gastric volvulus, rotating on the gastroesophageal, and pyloroduodenal junctions. The omentum was not overlying the stomach, typically seen in mesenteroaxial gastric volvulus. The body of the stomach was derotated with no evidence of gastric necrosis noted. The spleen was in the right cranial abdomen and returned to its normal anatomic position after derotation of the stomach. The patient recovered uneventfully and was discharged the next day. To the authors’ knowledge, organoaxial gastric volvulus has not been reported in dogs. This is rare in humans but occurs most commonly in children <5 yr of age associated with hernias. The recommended treatment is surgical in majority of cases. As a result of the unusual orientation of the stomach, the diagnosis of gastric dilatation-volvulus was challenging. Organoaxial gastric volvulus demonstrates the need for further imaging and evaluation in cases of persistent gas dilation.

A 76-year-old Japanese man was referred to our hospital with chief complaint of right hypochondoralgia. Abdominal ultrasound showed a retroperitoneal tumor in the suprarenal region of the right kidney. Computed tomography revealed an enhanced lobular tumor with irregular, circumscribed, and indistinct border. Ultrasound-guided biopsy was performed. The tumor consisted of spindle-shaped cells with a giant nucleus and multinuclear cells. The diagnosis was leiomyosarcoma by immunohistochemical staining. The patient underwent surgery accessed by a right eighth intercostal thoracoabdominal incision. The tumor was completely resected, accompanied by removal of the posterosuperior segment of the right hepatic lobe, right adrenal gland, and a portion of the inferior vena cava (IVC). The histopathologic diagnosis was leiomyosarcoma arising from the IVC. We present a rare case of a successfully managed leiomyosarcoma of the IVC. This case suggests the importance of curative surgical resection of the tumor due to low efficacy of adjuvant chemotherapy for leiomyosarcoma.

Retrocaval Ureter

Background: Retrocaval ureter also referred to as circumcaval ureter or preureteral venacava is a rare congenital anomaly with the ureters passing posterior to the inferior vena cava (IVC). The ureter classically course medially behind the inferior venacava winding around it and then passes laterally in front of it to then course distally to the bladder. Though it is a congenital anomaly, patients do not normally present with symptoms until the 3rd and 4th decades of life from a resulting hydronephrosis. This hydronephrosis may be due to kinking of the ureter. The ureteric segment is a dynamic or compression against the psoas muscle. It was initially considered as aberration in ureteric development; however current studies in embryology have led to it being considered as an aberration in the development of the inferior vena cava. Objectives: The aim of our study was to explore the safety, feasibility and usefulness of retroperitoneoscopic surgery for retrocaval ureter performed in a single centre and to assess the short-term outcomes of patients treated with this surgical approach. Materials and methods: Eight patients underwent retroperitoneoscopic transposition of ureter between March 2014 and November 2016, A 3-port, ballon-dissecting, retroperitoneal approach was used, no open conversion was required. Follow-up studies were performed with intravenous urography and ultrasonography. Results: Mean operating time was 121 minutes (range 92-178) and mean anastomotic time was 56 minutes for all cases. Blood loss was minimum. None of the patients required blood transfusion. No intraoperative complications occurred. Hydronephrosis in all patients were decreased substantially after surgery. Conclusion: Our results have demonstrated that retroperitoneoscopic transposition of ureter is an excellent minimally invasive treatment option for a retrocaval ureter that can be accomplished quickly and safely.

A 10-year-old, spayed female, mixed-breed dog was referred for evaluation of bilateral hindlimb edema and weakness. Abdominal ultrasonography showed increased echogenicity of the lumen of the caudal vena cava from the level of the urinary bladder to the level of the cranial pole of the right kidney. Bilateral saphenous venograms displayed numerous filling defects in the caudal vena cava, right external iliac vein, right femoral vein, and the right common iliac vein. Extensive venous thrombosis was diagnosed, and the animal was euthanized. Necropsy confirmed the presence of venous thrombosis and revealed a right adrenocortical carcinoma that had invaded the caudal vena cava.

Retrocaval ureter, also known as circumcaval ureter, is a rare congenital anomaly which commonly presents with loin pain in middle age group. Here, ureter passes between the inferior vena cava (IVC) and psoas muscle and gets compressed. Duplication of IVC is another rare congenital anomaly in the development of IVC. We present a case of a 49-year-old male who presented with loin pain and upon thorough investigation was found to have retrocaval ureter along with duplication of the infrarenal IVC. We bring forward this rare type of combination of two congenital malformations.

AbstractRetrocaval ureter is a rare congenital anomaly which has a incidence of occurence of one in 1500 live births. It is known to occur 2.8 times more commonly in males than females. While carrying out a study on congenital anomalies in urinary system in a collection of still born fetuses, a case of retrocaval ureter was noticed in a still born male foetus. In Retrocaval ureter, ureter is S shaped on the right side and a part of inferior vena cava is anterior to the proximal part of the ureter. Here the development of ureter is normal. Whereas the development of inferior vena cava is abnormal.
