BACKGROUND
Intravenous misplacement of a nephrostomy tube is a rare complication of percutaneous nephrolithotomy (PCNL) or percutaneous nephrostomy. The mechanism of misplacement of a nephrostomy tube into the vascular system is seldom investigated. One type of the possible mechanism is that the puncture needle penetrates a major intrarenal tributary of the renal vein and enters the collecting system. However, the guidewire is located outside the collecting system near the large branches of renal vein or perforates into the renal vein. The dilation is performed and causes a large torn injury. Subsequently, the nephrostomy tube is placed inside the vessel when radiological monitoring is not used. However, there is no imaging evidence and the scene of procedure is not demonstrated. This paper reports two cases of visualization of the renal vein filled with contrast agent during PCNL. The findings may be good evidence to support the step of renal vein injury in patients with intravenous nephrostomy tube misplacement.
CASE PRESENTATION
We presented two cases with visualization of the renal vein filled with contrast agent during PCNL. In the process of injecting the contrast agent through the puncture needle, we could see the renal vein. Moreover, it was identified that the puncture needle tip was not on the optimal position. The position of puncture needle tip lay outside the collecting system, which was close to the calyceal infundibulum and branches of renal vein.
CONCLUSIONS
Visualization of the renal vein filled with contrast agent may be good evidence to verify the renal vein injury in patients with intravenous nephrostomy tube misplacement during PCNL or percutaneous nephrostomy. The suboptimal location of the puncture needle tip and visualization of the renal vein filled with contrast agent indicate the renal vein injury. One type of mechanism of intravenous nephrostomy tube misplacement is as following. Firstly, the guidewire stays outside the collecting system. Subsequently, dilatation directed by the guidewire results in the injury of the vein. Then, the nephrostomy tube migrates into the venous system due to prompt tube inserting and the direction of the sheath and/or the guidewire to the injured vein.

Primary renal vein leiomyosarcoma (LMS) is a rare tumor with only a few cases reported in the literature. Clinical diagnosis of renal vein LMS can be difficult because of nonspecific symptoms and nonpathognomonic radiological features. The primary treatment modality is radical nephrectomy followed by chemotherapy and/or radiotherapy. There is scarcity of literature regarding prognosis because of rarity of tumor; however, tumor size (>3 cm) determines the risk of local recurrence and distant metastasis. Overall prognosis of renal vein LMS is poor. Here, we describe clinical and histopathological features of a 50-year-old female patient with LMS of right renal vein.

Nutcracker syndrome is a vascular anomaly consisting in the compression of the left renal vein between the superior mesenteric artery and the aorta. Clinical features in nutcracker syndrome include pelvic pain, flank pain, haematuria, gonadal varices or simply asymptomatic. We are presenting two cases, one of them with macroscopic haematuria and flank pain and the other was studied for hypertension but with previous antecedents of left renal vein embolization in the setting of varicocele. We discuss the clinical presentation as well as diagnostic and therapeutic aspects related to this syndrome.

Percutaneous nephrostomy is a critical procedure for establishing surgical pathways from the skin to the renal collecting system. The drainage tube involved in the procedure rarely deviates into the renal vein. Herein, we report three cases in which the related drainage tube was mistakenly inserted into the renal vein and inferior vena cava after the renal vein was injured during percutaneous nephrostomy. In the three cases, the nephrostomy tube and double-J tube were gradually withdrawn from the renal pelvis or renal calyces under computed tomography (CT) monitoring. In case 1, the fistula tube was not completely withdrawn in time into the renal, causing multiple thromboses in the vein. The fistula was successfully withdrawn from the vena cava after the filter was placed. Finally, the stones were cleared in two cases and one case was discharged without complications after substantial renal function recovery. A safe and reliable approach is to gradually withdraw, within a short timeframe and under CT monitoring, an ectopic renal vein or inferior vena cava drainage tube into the renal pelvis. Removal of the catheter to the renal pelvis or calyces within 3 days can reduce thrombotic complications.

PURPOSE
Renal vein anomalies are usually asymptomatic embryological developmental disorders. If unidentified, they can lead to significant morbidity during surgical explorations. This study aims to evaluate the type, frequency, clinical importance of renal vein anomalies in patients scanned with Multidetector Computed Tomography (MDCT). It was also investigated whether renal vein anomalies are associated with malignancies or their types.
METHODS
Abdominal MDCT images of 8517 patients were examined retrospectively. Renal vein anomaly types, gender, age, and symptoms were recorded. Renal vein anomalies were divided into three subgroups as retroaortic left renal vein (RLRV), circumaortic left renal vein (CLRV), and double right renal vein (DRRV). The presence of malignancy and their types in patients with renal vein anomalies were noted. Malignancies were divided into five subgroups as lung, gastrointestinal system (GIS), genitourinary system, breast, and others.
RESULTS
156 patients had renal vein anomaly (1.8%). The prevalence of RLRV, CLRV, and DRRV were 1.1%, 0.3%, and 0.2%, respectively. Renal vein anomalies were more frequent in females. Malignancy was present in 89 (57.1%) out of 156 renal vein anomaly patients. Among these 89 patients, RLRV was found in 52 (58.4%), CLRV in 22 (24.7%), and DRRV in 15 (16.8%) patients. The presence of malignancy was present in more than half of the renal vein anomaly patients but there was no significant correlation (p = 0.1). This high ratio is probably due to the high number of cancer patients undergoing CT scan in our radiology department.
CONCLUSIONS
Renal vein anomalies are rare conditions, however, coexistence of renal vein anomalies and malignancies is not. An awareness of this entity before retroperitoneal surgeries is very important in order to avoid complications such as hemorrhage, transfusion, death, or conversion to open surgery.
