A recent U.S. Public Health Service report compared the incidence of complications with 3 methods of midtrimester abortion. The comparison was based on a 4-year study of abortions done in 32 institutions. Major complications were least frequent with cervical dilatation followed by curettage or suction evacuation, more frequent with hypertensive saline injected into the amniotic sac, and most frequent with instillation of prostaglandin F2. By the second trimester, dilatation and evacuation is a difficult procedure. Major complications considered were: fever for 3 or more days; pelvic infections; pneumonia; thrombophlebitis; hemorrhage requiring transfusions; psychiatric hospitalization; hypernatremia; injury to bladder, ureter, or intestines; wound disruption; unintended major surgery; pulmonary embolism; convulsions; endotoxic shock; cardiac arrest; and death. The report is difficult to evaluate. Most medical letter consultants prefer intraamniotic administration of prostaglandin F2 or saline for midtrimester abortions.

The results of treatment of 41 children with vesical exstrophy were analysed. Four types of surgeries were performed: 1) transplantation of Lieutaud's triangle into the sigmoid (n = 19); 2) its transplantation into the semi-isolated part of the sigmoid (n = 7); 3) ureteral transplantation into the sigmoid (n = 3); 4) the formation of the urinary bladder and ureter from the adjacent tissues (n = 12). In the first group 2 children died, 6 patients had no clinical signs of chronic renal or ureteral inflammation for the period of 5-17 years, the remaining 11 patients had pyelonephritis. In the second group 5 children were apparently healthy for 1-3 years after the operation, one child developed pyelonephritis, one child died from pneumonia. In the third group 2 patients were apparently healthy 1.5-2 years after the surgery, 1 child developed pyelonephritis. A great number of complications such as sutural incompetence followed by fistulization or enuresis made the authors avoid the fourth type. Thus, while forming an urointestinal anastomosis, preference is given to transplantation of Lieutaud's triangle or ureters proper into the semi-isolated segment according to the antireflux methods, if there are strictures in their distal portions.

1. Widespread visceral and intestinal wall metastases are present in women dying with ovarian cancer. Intestinal wall invasion is commonly found at autopsy and is associated with bowel obstruction. Liver parenchymal replacement by metastases in more extensive than that in the lung, where most metastases have a subpleural location. Multifocality characterizes metastases in both of these organs. 2. Neoplastic lymphatic invasion is common. Lymphatic and blood vascular invasion are associated with an increased incidence of metastases in lymph nodes, small bowel wall, pancreas, lungs, ureter, and liver. 3. The mean survival time from diagnosis to death is less than 2 years. Both increasing neoplastic histological grade and clinical stage at diagnosis are associated with decreased survival time. 4. The most common causes of death are carcinomatosis, infection, or a combination of these processes. Sepsis, pneumonia, or both of these account for most of the fatal infections. 5. Bowel and ureteral obstruction constitute the most common forms of tumor-induced morbidity. The former process tends to be multifocal, involving the small and large intestines, and it is found during the disease course as well as at autopsy. Ureteral involvement is usually associated with hydronephrosis and is bilateral in approximately one fourth of the cases.

This 2-center study compares the relative merits of laparoscopic and open surgical internal marsupialization of pelvic lymphoceles. Laparoscopic lymphocelectomy was performed in 12 patients (group 1). The results were compared with open lymphocelectomy performed in 13 contemporary patients (group 2) as well as 13 historical patients (group 3). Operative time was longer in group 1 compared to groups 2 and 3 (194.6 versus 176.9 versus 133.8 minutes, respectively). However, group 1 had a decreased blood loss (23.1 versus 74.6 versus 61.7 ml.), earlier resumption of oral food intake (0.9 versus 2.5 versus 2.1 days), shorter hospital stay (2 versus 6.1 versus 6.3 days) and abbreviated convalescence (2.2 versus 6.9 versus 4.5 weeks) compared to groups 2 and 3. Complications included cystotomy requiring open repair in 1 patient in group 1, prolonged ileus in 1 in group 2, transection of the ureter of a transplant kidney in 1 in group 3 and pneumonitis in 1 in group 3. Lymphocele recurred in no patient in group 1, 4 in group 2 and 3 in group 3. Mean followup in groups 1 to 3 was 12.8, 25 and 54.5 months, respectively. We conclude that laparoscopic lymphocelectomy is effective, results in minimal patient morbidity and allows for a more rapid recovery compared to open surgical lymphocelectomy.

Renal transplantation was performed on 6 cats with chronic renal failure. Clinical signs and the blood chemistry findings (BUN, Cr, IP) improved one week after renal transplantation. Renal anemia also improved 3-4 weeks after surgery. Two cases had the same complications, hydronephrosis and hydroureter within 1 or 2 weeks of surgery, evidenced by marked elevations of BUN and Cr, suggesting that ureteral obstruction at the site of ureterocystostomy is the main complication of renal transplantation in cats. As a new resolution for this problem, we transplanted the ureter with the intact ureteral opening of the bladder from the donor in the remaining 4 cats. Ureteral obstruction was not observed in them, thus the procedure was considered to be useful for avoiding this complication. Two cats died of pneumonia and other complications within 3 months. There were no acute rejections or side effects from the immunosuppressant during the observation period in the remaining four cats.

Postmortem cross-sectional imaging using multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) was considered as a base for a minimal invasive postmortem investigation in forensic medicine such as within the Virtopsy approach. We present the case of a 3-year-old girl with a lethal streptococcus group A infection and the findings of postmortem imaging in this kind of natural death. Postmortem MSCT and MRI revealed an edematous occlusion of the larynx at the level of the vocal cords, severe pneumonia with atelectatic parts of both upper lobes and complete atelectasis of both lower lobes, purulent fluid-filled right main bronchus, enlargement of cervical lymph nodes and pharyngeal tonsils, and additionally, a remaining glossopharyngeal cyst as well as an ureter fissus of the right kidney. All relevant autopsy findings could be obtained and visualized by postmortem imaging and confirmed by histological and microbiological investigations supporting the idea of a minimal invasive autopsy technique.

Two centuries have now passed since the birth of Joseph Dietl, whose uncommon ability, industry, inexhaustible energy, dogged perseverance, and courage contributed to the development of medical science in Europe. He also contributed to reform of the educational system, and to bringing order to the badly neglected city of Cracow. He belonged to the so-called New Vienna School of Medicine. Dietl, chief physician at the Wieden Hospital in Vienna since 1941, had voiced his disbelief in the existing therapy in such strong terms that it was recorded in the history of medicine as the program of therapeutic nihilism. Dietl demonstrated experimentally in Vienna and Cracow that bloodletting in pneumonia is not indicated, since it does not promote recovery and is indeed harmful, raising mortality rates three times compared to those patients who had received dietary treatment only. He eliminated bloodletting in pneumonia therapy. Dietl was the first to investigate and classify Galician and Silesian therapeutic springs as well as work out detailed prescriptions for spa treatments. He understood that treatment in a health resort could not be limited to balneotherapy, and he indicated that climatotherapy and physiotherapy should also play a role. Dietl described the crisis attributable to a kink in the renal vessels or ureter when the kidney dropped. It was also Dietl who gave a description of the floating kidney problem and of kidney partial incarceration, a condition still known as Dietl's crisis. He recommended conservative therapy for these cases.

Dermatomyositis is a rare inflammatory myopathy that has characteristic cutaneous lesions. Although many malignancies are associated with dermatomyositis, urogenital malignancies have rarely been reported to be associated with dermatomyositis. We report here on the first case of ureteral cancer associated with dermatomyositis. A 42-year-old man presented to us with a skin rash. A clinical diagnosis of dermatomyositis was made due to the skin lesions, muscle weakness, arthralgia, the increased erythrocyte sedimentation rate and the increased creatine kinase level. The patient revealed microscopic hematuria and abnormal urine cytology during the investigation for the underlying malignancy. Retrograde pyelography demonstrated a suspicious lesion in the right mid-ureter, and the ureteroscopic biopsy revealed the urothelial carcinoma. Although an operation was recommended, the patient died of pneumonia associated with his interstitial lung disease, which is one of the poor prognostic indicators of dermatomyositis.

A 79-year-old female admitted as a result of respiratory insufficiency due to pneumonia presented with a painful swelling in the left lumbar region and acute ureteral colic pain. The diagnosis of Grynfeltt's bilateral hernia was made by means of CT, which revealed herniation in the left side of the renal pelvis and proximal ureter.

Endoscopic ureterolithotomy was made in 38 patients who had concrements in the upper third of the ureter more than 1 cm in size. Operations were retroperitoneoscopic and laparoscopic in 20 and 18 cases, respectively. Five patients had recurrent stones, 7 patients had prior extracorporeal shock-wave lithotripsy, 2 patients failed contact ureterolithotripsy. In the rest cases endoscopic ureterolithotomy was a first-line treatment. A complete elimination of the stone was achieved in all the cases. Mean time of the operation in a retroperitoneoscopic approach was 149 min, in laparoscopic - 125 min. Mean blood loss was the same. Conversion was performed in one case in the group of retroperitoneal approach. Postoperative stay in hospital in retroperitoneo- and laparoscopic ureterolithotomy was 3 - 16 days. Laparoscopic ureterolithotomy produced a complication in one case - an insignificant injury of the colon. Urinous infiltration and pneumonia developed after retroperitoneoscopic ureterolithotomy in one and one case, respectively. Thus, endoscopic ureterolithotomy in large stones of the upper third of the ureter via retroperitoneal and transperitoneal approach is a safe, low-invasive and effective operation which provides complete stones elimination. Endoscopic ureterolithotomy should be done in uneffective first-line treatment. It is a leading method in the treatment of large and long-standing stones of the upper third of the ureter.
