One encounters a variety of radiopaque foreign objects when reviewing plain film radiographs of the abdomen. Recognizing such devices can offer important clues about a patient's medical history. Accordingly, intrauterine contraceptive devices (IUCD), tubal sterilization, varicoceles, inferior vena cava (IVC) filtration, and vaginal pessaries are discussed with reference made to an IUD, tubal sterilization clips, embolization coils for bilateral varicoceles, an IVC filter, and a vaginal pessary in five attached anteroposterior radiographs of the lower abdomen and pelvis for five different patients. IUCDs confer long-term, passive, reversible, and inexpensive protection against unwanted pregnancy. They may, however, induce menstrual complications as well as an increased risk of pelvic inflammatory disease and ectopic pregnancy. They can also be spontaneously expelled from the uterus without being noticed by the client. An IUCD increases the risk of spontaneous abortion unless removed in cases where intrauterine pregnancy occurs. Complications at the time of insertion include pain, syncope, and uterine perforation. Tubal sterilization is an effective, though largely irreversible method of contraception. Complications include an increased risk of ectopic gestation in the event of pregnancy and the usual risks of hemorrhage, infection, injury to adjacent structures, and anesthesia-related complications. A varicocele is a dilation of the pampiniform venous plexus of the scrotum. They are more often unilateral than bilateral, occurring in up to 20% of men most often on the left side. Although most cases are probably insignificant, varicoceles can decrease sperm count and motility and cause abnormal morphology. Correction of varicoceles has been shown to improve sperm quality and can increase the chances of fertility. Percutaneous venous embolization techniques have recently been developed to that end. Procedural risks include perforation of the vein, intimal dissection, inadvertent embolization of vessels via collateral channels, and reactions to contrast media. IVC filters are a feasible alternative treatment for deep venous thrombosis and pulmonary embolism among patients in whom anticoagulants are contraindicated or for those in whom anticoagulation therapy has failed. Introduced via the femoral or jugular veins, they are permanent metallic devices placed within the lumen of the IVC to filter thrombi which migrate from the deep veins of the lower extremities. Contraindications to IVC filter insertion include severe coagulopathy and thrombosis involving all venous access routes, while complications include hematoma at the insertion site, migration or tilting of the device due to poor anchoring in the IVC wall, and vena cava obstruction. A pessary is a prosthetic device used to support pelvic structures when their natural support is lacking. They are usually made of plastic or rubber and inserted into the vagina to aid in the non-operative treatment of uterine prolapse, proctoceles, and cystoceles. They must be properly fitted and removed every few months for cleaning.

Preliminary experience with uro-laparoscopy was retrospectively analyzed to determine whether patients profited from the laparoscopic procedure. Between August 1991 und July 1993 we performed 53 operations laparoscopically. Four more began in this way but ended in open surgery. 29 varicocele procedures were carried out. A reduced postoperative morbidity, and hence a benefit, were obvious in 3/29 patients with bilateral varicocele, but probably not in the remaining 26/29 patients affected only on the left side. 13 pelvic lymphadenectomies in patients with prostatic carcinoma T1-3, elevated prostatic acid phosphatase, a PSA > 30 ng/ml and/or a suspected N+ on CT, served to identify 10 pN0 and 3 pN1 patients. Four of the pN0 patients with a T3 tumor were given radiotherapy. Six with a T2 tumor underwent radical prostatectomy, four with margin-negative specimens benefited from laparoscopic lymphadenectomy by securing a curative operation which according to established rules would otherwise have been withheld. Two patients with margin-positive specimens suffered harm from laparoscopic lymphadenectomy, which had led to a needless operation. Another lymphadenectomy performed on one more patient suffering from deep venous thrombosis of the left leg associated with pelvic lymphadenopathy established the benign histology of the enlarged lymph nodes with minimal morbidity. 10 nephrectomies were carried out for benign, clinically relevant lesions of the kidney, which are rare. They produced a clear-cut benefit for all patients as the postoperative morbidity was minimal. We conclude that the present indications for uro-laparoscopic procedures are either disputable or rare.(ABSTRACT TRUNCATED AT 250 WORDS)

May-Thurner syndrome is a rare clinical entity involving venous obstruction of the left lower extremity. May-Thurner syndrome most commonly presents with deep vein thrombosis. We describe an unusual presentation of a girl with a dragging abdominal pain mimicking the symptoms of a varicocele. Diagnosis can be made with MR venogram. There are many different treatment options but if compression of the vein is minimal conservative management is possible.

Interventional radiology employs image-guided techniques to perform minimally invasive procedures for diagnosis and treatment. Interventional radiology is often used to place central venous catheters and subcutaneous ports, with some evidence of benefit over surgical placement. Arterial embolization procedures are used to manage many types of hemorrhage and are highly effective for severe postpartum hemorrhage. Vascular interventions, such as endovascular treatment of varicosities, acute limb ischemia, and pulmonary embolism, are superior to surgical interventions. For chronic limb ischemia and deep venous thrombosis, the choice of therapy is not as clear. Inferior vena cava filters can be placed and removed endovascularly, but there is a significant risk of complications that increases over time. Vascular interventions can be effective for scrotal varicocele and uterine fibroids, although fibroid treatment is limited by high recurrence rates. Image-guided percutaneous drainage and biopsy have become standard of care. Interventional approaches are being used in oncology for local diagnosis and treatment. Percutaneous ablation and targeted delivery of chemotherapy and radiation therapy are being developed as alternatives when surgery is not practical. Vertebroplasty and kyphoplasty provide significant pain and functional improvement in patients with spinal metastases.
