“…The treatment of retroperitoneal tumors is challenging, mainly because of their anatomical location, dimensions, and involvement of blood vessels or adjacent organs [ 13 , 14 ]. Considering the high proportion of malignancies, a well-planned surgery conducted by an experienced oncologist is important.…”

Leiomyoma is the most common benign neoplasm of the reproductive organs in women. Retroperitoneal hydropic leiomyoma is rare type of myoma. Herein, we present the case of a 46-year-old (gravida 0) woman with retroperitoneal hydropic leiomyoma that was preoperatively diagnosed as an ovarian cyst. Transvaginal sonography and abdominal computed tomography revealed a mass, measuring 8.1 × 3.8 cm , with solid and cystic components in the right pelvic cavity. The patient underwent laparoendoscopic single-site surgery for the tumor excision. During the surgery, a retroperitoneal cystic tumor was resected from the right retroperitoneal cavity. Histopathologic and microscopic examinations revealed a hydropic leiomyoma with infarction. This case is impressive because of the rare location and hydropic degeneration of the leiomyoma. Furthermore, it mimicked an ovarian cyst at its initial presentation making accurate diagnosis difficult. By warning of this case, surgeons can recognize the disease entities and provide the necessary treatment.

“…Smaller tumors (less than 5 cm) are usually "clinically silent" and are discovered accidentally the majority of the time [11,12]. As the tumors grow (over 10 cm), symptoms appear due to compression or invasion of the adjacent organs [13][14][15][16][17].…”

A 54-year-old man was seen in the clinic with the chief complaint of epigastric pain radiating to the left groin region and a predominant postprandial abdominal discomfort. Upon examination, a painless round mass with reduced mobility was felt in the left flank during deep palpation of the abdomen. His past medical history was irrelevant. Ultrasound and IV contrast-enhanced CT scan confirmed the presence of a large tumor and an exploratory laparotomy for removal of the tumor was performed. The microscopic examination of the specimen confirmed the primary diagnosis of retroperitoneal tumor (RPT) and identified it as an extragonadal germ cell tumor with a vestigial origin, which is a rare type affecting the kidney and adrenal gland. Primitive RPTs are histologically classified as mesenchymal and neuroectodermal or vestigial. These histological types are rarely found in surgical practice and are challenging to diagnose and treat due to the peculiarities of the site of origin where they develop. RPTs are extremely rare and approximately 80% are malignant and detected lately during the disease's course, commonly discovered in advanced stages of local or systemic evolution. Currently, surgical intervention remains the only effective method of treating these tumors.

“…This shows that obstructive uropathy with deterioration of renal function can occur in patients with retroperitoneal tumors which can be initially managed with ureteric decompression which is in accordance with our study. In another study by Lee et al, 41 patients were treated for retroperitoneal tumor, out of whom 21% patients received adjunct ureteral stenting [23].…”

Retroperitoneal tumors can cause ureteric obstruction leading to obstructive uropathy. Early preoperative ureteric stenting helps to improve renal function and also helps in identifying ureters and prevent ureteric injury during surgery. This study was aimed at assessing the outcome of preoperative stenting in optimizing such patients. A total of 24 cases were enrolled. Of these, 15 patients who had obstructive uropathy were taken for ureteric stenting preoperatively and other 9 patients have undergone surgery without stenting. Twelve patients were stented successfully but 3 patients could not be stented (underwent percutaneous nephrostomy). All 24 patients underwent laparotomy, and of the 12 stented patients, 11 underwent successful resection and one had unresectable tumor. The patient's serum creatinine was assessed initially and then twice after stenting (48 h and 5 days). Serum creatinine was also estimated 24 h after excision of the tumor. In the successfully stented and operated patients, mean initial creatinine was 7.85. The mean creatinine at 48 h and 5 days after stenting was 4.29 and 1.19 respectively. The mean creatinine 24 h after resection of the tumor was 1.04. Of the non-stented patients, 3 had ureteric injury during surgery. We conclude that preoperative ureteric stenting is helpful for optimization of patients with retroperitoneal tumors with obstructive uropathy.
