The uroradiological changes and complications with 110 patients who did undergo a total of 119 renal transplantations are discussed under the following 4 topographical headings: perirenal and intrarenal, ureter including the anastomosis, bladder, urethra. In our material we found a lymphocele in 1 patient, papillary necrosis in 3, ureteral obstruction in 6, urinary leakage in 23, reflux in a total of 23, renal calculi in 1 and bladder concrements in 1.

In 285 renal transplantations, performed during the years 1967-1978, 6 ureteral obstructions (2,1%) and 15 urinary fistulas (5,3%) were observed. Ureteral obstructions occurred in the late phase after transplantation and were caused by strictures at the uretero-vesical anastomosis (two patients), compression of the ureter by enlarged kidney during rejection (one patient) resp. lymphocele (one patient) and strictures at the pyelo-ureteral junction (two patients). Satisfactory results were achieved by surgical treatment in all patients. Urinary fistulas occurred in the early postoperative phase. Two vesical, 12 vesico-ureteral and one calyceal fistula were observed. 7 fistulas (1 vesical, 6 vesico-ureteral) closed spontaneously after temporary drainage of the bladder. 8 fistulas were repaired surgically. While satisfactory results were obtained in 13 patients, two patients died due to infection and sepsis after reoccurrence of fistulas.

A case of renal transplantation is presented in which ultrasound was used to detect and control the puncture and aspiration of a renal abscess and a lymphocele. Subsequently, the combined sonographic-radiographic technique was used to diagnose and demonstrate the site of obstruction of the ureter. Ultrasound, in combination with fine-needle puncture when necessary, has many advantages in the management of renal transplantation.

Lymphoceles as seen after renal transplantation are cystic swellings filled with lymph, situated beneath the lower end of the transplant on the iliac vessels. It seems that the lymph originates from lymphatics cut during operation. 5 such cases have been seen in our series of 268 renal allotransplantations. Symptoms arose 1 to 6 months after transplantation. According to our own experience and to 39 cases of the literature, deterioration of renal function because of compression of the ureter is the most common symptom. Therefore, intravenous pyelography is the main diagnostic means. Some cysts can be visualized by lymphangiography. Marsupialisation to the peritoneal cavity is the treatment of choice.

Trauma to a graft by a seat belt in a young adult, 18 months after transplantation. Drainage shortly after of a voluminous perirenal haematoma, abundant discharge of lymphorrhoea taking two months to resolve. Good recovery of the graft from both a radiological as well as biological standpoint. 4 years after the trauma, leucocytes in the urine associated with impairment of function of the graft. Discovery of a large hydronephrosis related to retro-peritoneal fibrosis. Ureterolysis with resection of the affected part of the ureter followed by anastomosis. Return to normal of renal function with disappearance of the hydronephrosis. Lymphocoele, a rare complication of renal transplantation, is discussed from three viewpoints: aetiopathology, diagnosis and treatment.

The same radiosurgical treatment was given to 108 cases of stages T1 and T2 uterine cancers, and consisted of curietherapy followed by an extended colpohysterectomy with lymph node resection (Meigs operation) Intravenous urography was performed during operation in all patients, and at least one postoperative intravenous urography was also carried out. Stricture of the pelvic ureter was discovered postoperatively in 50.9% of cases, with or without subjacent stasis: this type of image is transient and disappears within eight months. A lymphocele can cause images showing signs of bladder pressure. Ureteral and vesical complications of a true and definitive nature are extremely rare.

We retrospectively reviewed the charts of 150 consecutive patients who underwent renal transplantation at our institution in 1990 to determine the effectiveness of our pre-transplantation urological evaluation. Of 100 patients who met the inclusion criteria 74 were evaluated solely with a history and physical examination, urinalysis and a urine culture, while the other 26 underwent additional tests because of either a history of urological problems or abnormalities at the initial evaluation. Urological complications occurred in 18 patients. In 10 patients the complications were related to the operation and included postoperative hematuria from bleeding at the site of the ureteral reimplantation, symptomatic lymphocele formation and urinary fistula resulting from necrosis of the distal ureter. These complications could not have been anticipated by the pre-transplant evaluation. Urological complications in the other 8 patients were a febrile urinary tract infection (4), temporary urinary retention (2), hematuria and back pain requiring bilateral native nephrectomy (1), and lower tract obstructive symptoms (1 who eventually required transurethral resection of the prostate 15 months after transplantation). Only 1 of these complications might have been averted with more extensive preoperative testing and in none of these patients did the urological complication compromise allograft function. We conclude that most patients with end stage renal disease require only minimal evaluation before renal transplantation. More extensive evaluation is necessary only in patients with a strong history of urological disease or with abnormalities found during the basic examination.

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.

The development of a lymphocele is an uncommon but well-documented complication of renal transplantation. In most patients, lymphoceles remain asymptomatic, and no intervention is required. In some cases, however, lymphoceles become symptomatic and cause systemic and local manifestations. Ultrasonic scanning can easily diagnose and locate the size and position of perirenal fluid collections. Many of these patients can be managed conservatively by aspiration and drainage of the lymphocele under radiologic guidance. However, if the lymphocele remains symptomatic or reaccumulates after aspiration and drainage, surgical intervention may be required. We describe two different ultrasound-guided laparoscopic techniques for drainage of a perirenal lymphocele into the peritoneal cavity. Successful drainage was accomplished in 5 patients, with 1 patient suffering an injury to the ureter of the transplant kidney. Recommendations regarding patient selection and operative technique are presented.

Lymphocele is a most common surgical complication following renal transplantation. The indication for treatment is given when the lymphocele becomes symptomatic. We succeeded in laparoscopically deroofing large lymphoceles in nine patients that were causing ureter compression in eight and ipsilateral leg edema in six cases. The postoperative course was uneventful, and the surgery-related hospitalization did not exceed 7 days. Severe adhesions and a thick lymphocele wall, which made preparation difficult, resulted in the transection of the transplant ureter in one case. Techniques and prerequisites that would help to avoid this type of complication are discussed. According to CT scan or sonography, there was no recurrence in any of the patients after a mean follow-up of 11 months. This technique seems to be superior to other methods of treatment because not only is a cure obtained with a single intervention, but there is also a low risk of infection and a short hospitalization.
