Between 1969 and 1984 a radical prostatectomy was performed in 175 patients for localized carcinoma of the prostate. This corresponds to a percentage of 18,2% of 962 patients with cancer of the prostate admitted to this hospital during the same period of time. The intra- and postoperative complications following radical prostatectomy in this series of 175 patients are analyzed. In 144 patients a retropubic prostatectomy was performed, whereas in 31 patients the perineal approach was utilized. There was a mortality rate of 1.1% (2 patients). Rectal injuries in 7 patients and ureteral transsection in 2 patients accounted for intraoperative complications. In the early postoperative period non-fatal pulmonary embolism occurred in 4 and myocardial infarction in 3 patients. In 3 cases (1,7%) a transitory hemodialysis became necessary because of renal insufficiency. Lymphoceles had to be treated in 22 patients (12,6%) and hematomas in 9 patients (5,1%). Persistent total urinary incontinence was observed in 8 patients (5%) and stress incontinence of varying degree in 25% of cases. The causes of these complications are analyzed and possible ways of preventing and treating them are discussed.

Lymphocele formation is a recognized complication of renal allotransplantation that can jeopardize the graft and cause major morbidity for the allograft recipient. Previously, emphasis has been placed on treatment as opposed to prevention. We attempted to prevent lymphocele formation by adopting 2 techniques in performing the renal transplantation: 1) we limited the area of dissection in the recipient to that necessary to obtain vessel control of the segment of iliac vessel that was to be used for the vascular anastomosis (to decrease the number of lymphatics that were divided or destroyed) and 2) we practiced lymphostasis as meticulously as we did hemostasis. We did not attempt to ligate any lymphatics in the hilus of the kidney. Using these techniques we have performed 198 consecutive renal allografts without the development of an identifiable lymphocele. The limitation of the area of vessel dissection has not increased either the rate of major vascular complications (2 per cent) or the development of major pulmonary embolism (0.5 per cent) after transplantation. We conclude that extensive dissection of the iliac vessels is not necessary to prevent major vascular complications or pulmonary emboli after renal transplantation, that careful lymphostasis in the allograft recipient will prevent the development of a lymphocele and, therefore, that the lymph fluid in a lymphocele is derived primarily from the allograft recipient and not from the allograft itself.

Staging pelvic lymphadenectomy (PLND) was performed in 210 prostatic cancer patients (mean age 67 years, clinical stage T0-T3 M0). A radical retropubic prostatectomy was subsequently performed in 54 men, ten of whom also received postoperative radiotherapy due to positive surgical margins. Ninety-eight patients were treated with external beam radiation alone (70 Gy in 35 fractions) and the remaining 58 received endocrine therapy. The complications of PLND alone (156 patients), consisted of wound infection in eight patients, hematoma or lymphocele in seven, venous thrombosis in three, and cardiac infarction in one patient. Early side-effects of radiotherapy included mild to moderate proctitis and/or cystitis in 57 patients. One year after completion of therapy, 48 of the irradiated men had proctitis, but only six had severe symptoms. Four patients developed radiation cystitis and two urethral stricture. Following prostatectomy (54 patients), two patients died in pulmonary embolism and another one developed a deep venous thrombosis. Hematoma occurred in five patients. Of the 42 surviving patients who did not receive postoperative radiotherapy, eight developed anastomotic strictures and four had severe stress incontinence. Only five were fully potent one year after surgery. Eight of the ten patients receiving radiotherapy after prostatectomy developed side-effects from the intestine and/or the urinary bladder. Two of them became totally incontinent. One developed a severe hemorrhagic cystitis necessitating urinary diversion. All ten were impotent after treatment.

The intraoperative, immediate postoperative, and late postoperative morbidity and prostate-specific antigen (PSA) levels in 511 consecutive patients with clinical T1b, T1c, and T2 tumors, who underwent anatomical radical retropubic prostatectomy, have been discussed. Between 1988 and 1995, prostatic cancer was diagnosed in 511 patients on the basis of PSA and prostate biopsy, when life expectancy was more than 10 years and frozen sections of obturator lymph nodes were negative. All specimens were cut into 3 mm sections by the step-section technique, after the surgical margin had been inked with formalin-resistant dye to identify the margin status. The mean age of the 511 patients was 63.4 years. Blood loss during the operation decreased to 986 ml in the last 2 years. Of the patients, 4.3% had intraoperative rectal perforation; only 5 required a second operation, which was done with a simple rectal approach. Ureteral injury occurred in 1.4% and this was repaired during the operation; 11% had prolonged lymphocele; all were treated conservatively. Deep-venous thromboses were seen in 3.7%; 5 patients (1%) had pulmonary embolism, which was lethal in 3 patients (0.6% of the whole group). There were no intraoperative deaths. No patient death was observed in the last 3 years, when all lymphoceles were diagnosed with thorough ultrasonographic evaluation and drained immediately. Complete continence after 1 year was achieved in 92% of the patients; 5.8% of the patients had anastomotic stricture; most were treated with a single calibration. Twelve months after the operation, 80% of the patients had no measurable PSA. There was a clear correlation of PSA negativity to tumor stage. Anatomical radical prostatectomy is safe and can cure about 70% of patients with clinical T1b, T1c, and T2 prostatic tumors.

Analysis of early and late post-surgical complications in 44 cases of Studer's type bladder replacement due to carcinoma of the bladder performed over a 6-year period. Follow-up ranges between 6 months and 6 years. 4 patients died during the post-operative (9.09%): 1 myocardial infarction, 1 pulmonary embolism and 2 intestinal fistula. 28 patients (63.64%) had post-operative complications: 4 GI fistula (9.09%) 5 ileus (11.36%), 2 GI bleeding (4.54%), 1 ureteral fistula (2.27%), 1 ureteral stenosis, 6 urethro-intestinal fistula (13.36%), 1 tubular necrosis, 1 ruptured ureteral catheter, 5 wound infections (11.36%), 12 urine infections (27.27%), 6 sepsis (13.63%), 1 lymphocele, 1 evisceration and 2 eventrations. Repeat surgery was required in 6 cases. Within 6 months from discharge, 7 of 40 patients (17.5%) had some complication: 3 acute pyelonephritis, 4 episodes of acidosis-dehydration and 1 ureter stenosis. After 6 months, 7 of 38 patients (18.4%) had complications: 1 acidosis, 3 vesical lithiasis, 2 ureteral stenosis and 1 urethro-intestinal, plus 2 cases of chronic urinary retention. Daytime continence was 97.2% and nighttime continence 30%; after 6 months evolution, no further changes were seen.

A 66-year-old man was admitted with distal edema of his right leg. He had undergone radical prostatectomy and pelvic lymphadenectomy for prostatic cancer 23 days previously. Abdominal computed tomography (CT) showed a lymphocyst (4.5 x 3.0 cm) along the right pelvic wall compressing the right external iliac vein. CT with contrast medium showed thrombus formation (about 9 cm) in the distal portion of the right external iliac vein and femoral vein. An inferior vena cava filter was placed to prevent pulmonary embolism, and anticoagulation with warfarin was started. One week later, CT showed shrinkage of the lymphocyst and thrombus in the vein, as well as a large thrombus trapped in the filter. Follow-up CT taken 2 months later revealed marked reduction of the lymphocyst and absence of thrombus in both the vein and filter. A lymphocyst, also known as a lymphocele, is a complication of radical pelvic surgery. Most lymphocysts are asymptomatic and regress spontaneously, but may lead to deep vein thrombosis and pulmonary embolism, usually a few weeks after surgery. Careful observation is needed even after discharge from hospital.

This article focuses on the role of interventional radiology in the therapeutic and diagnostic management of benign and malignant gynecologic conditions. The subspecialty of interventional radiology utilizes minimally invasive advanced image-guided percutaneous techniques in gynecology that include central venous catheter placement, fluid aspiration, drainage catheter placement, tissue biopsy, inferior vena cava filter placement, and pelvic arterial embolization. Central venous catheters, such as ports, peripherally inserted central catheters, and tunneled catheters, are placed for intermediate to long-term intravenous chemotherapy or total parental nutrition or antibiotics. Patients with refractory malignant ascites or pleural effusion from seeding of advanced gynecologic cancers may benefit by percutaneous aspiration of fluid collections or placement of drainage catheters. Postoperative fluid collections including abscess, seroma, or lymphocele are managed by percutaneous drainage catheter insertion. Pelvic, peritoneal, or retroperitoneal masses can be sampled by image-guided percutaneous biopsy or aspiration of fluid to determine a pathologic diagnosis. Certain patients are at risk for deep venous thrombosis with pulmonary embolism and may benefit from an inferior vena cava filter. Patients with uncontrolled postoperative or postpartum bleeding can be effectively managed with emergent transarterial pelvic embolization. Each of the aforementioned interventions with indications, expected benefits, and complications is described including a published literature.

Pulmonary embolism is a frequent and mortal situation especially in high-risk patients. Although thrombolytics and anticoagulants are the main options in treatment, substantial portion of patients also have high bleeding risk. Therefore, new catheter-directed treatment strategies, such as ultrasound-assisted transcatheter thrombolysis, gain importance in treatment options for intermediate and high-risk patients. Here, we report a case of massive pulmonary embolism due to the iatrogenic lymphocele after a radical retropubic prostatectomy procedure. The usage of ultrasound-assisted transcatheter thrombolysis was successful in such a high-risk patient.
