The authors studied hydronephrosis characteristics for horseshoe kidney in 170 patients aged 15-70. Basing on anatomic and functional features and urethral condition in each patient 136 operative interventions on one or two parts of the fused kidney in 125 patients were conducted. 26 heminephrectomies were carried out in hydronephrosis stage III, pyonephrosis and acute purulent focal pyelonephritis. 110 stage I-II hydronephrosis patients underwent an original reconstructive combined surgery on the fused kidney ending in formation of two separate organs. High incidence of hydronephrosis in horseshoe kidney against that in normal kidney (64 and 7%, respectively) and not infrequent bilateral involvement (63%) can be explained by anomalous structure of the organ conducive to obstruction of the urinary tracts. In 136 surgical cases the obstruction was due to: peripelvic compression of the ureter above the isthmus of the kidney (128 cases), high branching of the ureter from the renal pelvis with formation of the "spur" (114 cases), periurethritis and the fixed peripelvic ureteral kink by the adhesions (64 cases), congenital stricture of the peripelvic ureter (42 cases) or its compression by the accessory vessel (12 cases). To correct these abnormalities, it is reasonable to employ reconstructive surgery proposed by E. M. Shimkus. The procedure implies the isthmus resection with renal segment part, resection of the lower calyx, pelvic plasty according to Anderson-Hines technique, pyelolithotomy and nephropexy. This surgery abolishes all the underlying causes of fused kidney hydronephrosis and reestablishes urodynamics. It secured positive results by 2-28-year follow-up in 95% of the patients and is recommended as a method of choice.

A bifid blind-ending ureter is an extremely rare congenital anomaly of the upper urinary tract. This unusual ureteric condition appears to be more common in female subjects. Such patients may be asymptomatic or present with recurrent urinary tract infections, frequency, nycturia, abdominal pain or calculi. Asymptomatic patients without urinary tract infection require no treatment. When symptoms or infection are present, the treatment is surgical excision of the blind branch with antireflux reimplantation of the normal ureter. If hydronephrosis, pyonephrosis or renal damage is present, nephroureterectomy may be required.

The very rare occurrence of ascariasis of the kidney is reported in a 6-year-old boy from Cape Town, South Africa. He was acutely ill with pyonephrosis and passed adult Ascaris lumbricoides per urethra before having a nephrectomy. There was no evidence of a fistula between the intestines and the urinary system, and as the development of larvae into mature helminths within the renal system is not considered to be possible it is likely that mature worms gained entrance through the urethra. It appears that the worms obstructed the right ureter and caused hydronephrosis, pyonephrosis, and deposition of ova in renal tissue.

We were interested in the efficacy and morbidity of the ureteroscopy (URS) in the treatment of "steinstrasse" after ESWL. From 1991 to 1996, 27 patients with "steinstrasse" were treated with a total of 32 ureteroscopic procedures. The URS alone had a stonefree success rate of 43.7% (n = 14). URS combined with ESWL was effective in 43.7% (n = 14), leading to an overall success rate of 87.4%. In 4 cases (12.6%) a second therapy was necessary (in 3 cases a second URS + ESWL and in one patient a nephrectomy due to septic pyonephrosis. The overall rate of auxiliary ESWL after URS was 53.1%. Mean operating time was 72 minutes (20-180 min). The rate of complications was 21.8% (n = 7) and mainly due to ureteral perforations or postoperative fever but none suffered from late complications like ureteral stricture. All treated patients received a double-J-stent and antibiotics. The treatment of "steinstrasse" in the middle portion of the ureter proved to be more difficult due to the anatomical position of the ureter and lasted in a longer operating time as the upper or distal "steinstrasse". The stone extraction and the lithoclast-lithotripsy alone or in combination were the most frequent used ureteroscopic procedures to eliminate stone fragments. The URS alone or in combination with the ESWL for the treatment of "steinstrasse" is a highly effective and safe approach.

A case of pyonephrosis with high levels of serum CA19-9 antigen is reported. A 71-year-old woman was admitted with right flank pain. Computed tomography and ultrasonography showed severe hydronephrosis and hydroureter due to a right ureter stone. Laboratory data revealed a high level of serum CA19-9. However, no tumor was found in the pancreas, gallbladder, liver, gastrointenstinal tract or genitourinary tract. Drip infusion pyelography showed a non-functioning pattern of right kidney. Therefore, right nephroureterectomy was performed for right pyonephrosis. Histological examination revealed chronic inflammation. Malignant cells were not seen in the resected specimen. The serum CA19-9 levels before and after operation were 102.9 U/ml and 24 U/ml, respectively, being normal after the operation. Immunohistochemical examination revealed the presence of CA19-9 antigen in the urethelium, indicating its expression in the specimen. To our knowledge this might be the first case of pyonephrosis associated with high levels of serum CA19-9 antigen.

Nephrectomy is a radical operation successfully used over more than a century. It should be resorted to only in exceptional situations whenever an organ salvaging operation is precarious for the patient's health (T Patrashkov, 1980). The indications for nephrectomy depend on the type of disease, extent of renal damage, state of the second kidney and the patient's general condition, established by the basic examination methods in urology (T Patrashkov 1982). The study covers 388 nephrectomies in cases presenting diverse diseases of the kidney and ureter, diagnosed and treated in the Department of Urology--University Hospital "Alexandrovska" in the period 1990 to 1995. The commonest causes leading to nephrectomy comprise: 1. Neoplasms of kidney and ureter--134 (34.54%). 1.1. Parenchymal tumors--116 (29.90%)/ 1.2. Papillary tumors--18 (4.64%). 2. Pyonephrosis--88 (22.68%). 3. Nephrolithiasis (presence of renal calculi)--53 (13.66%). 4. Secondary operations of the kidney and ureter--46 (11.86%). 5. Hydronephrosis--38 (9.80%). 6. Anomalies (hypoplasia)--8 (2.06%). 7. Cystic diseases--7 (1.80%). 8. Tuberculosis of kidney--6 (1.55%). 9. Renovasal hypertension--4 (1.02%). 10. Nephrectomy for other diseases--4 (1.02%). As shown by the results the rate of nephrectomy undertaken for renal malignancy is still the highest which is by no means considered as a favourable diagnostic sign.

A 55-year-old woman who had undergone left nephrectomy 7 years prior because of pyonephrosis, suffered from refractory cystitis and was diagnosed with empyema of the left ureteral stump associated with ectopic ureter. Although removal of the stump is a popular treatment for this disease, transurethral fulguration of the stump lumen was performed in the patient described here. The procedure was technically easy and safe, resulting in the disappearance of the dilated stump and cessation of recurring cystitis.

A case of primary carcinoma of the remaining ureter is reported. A 70-year-old man presented with asymptomatic gross hematuria. Three years ago, he had received right nephrectomy for pyonephrosis. Although drip infusion pyelography (DIP) and cystoscopy showed no abnormal findings, computed tomography (CT) and retrograde ureterography demonstrated the irregular thickening of the right remaining ureteral wall. He underwent right ureterectomy with bladder cuff resection. Pathological examination revealed transitional cell carcinoma of the remaining ureter. He has been free of disease for 3 years.

Reported here is the case of a 72-year-old renal transplant recipient with stenosis of the neo-ureter requiring stents, who was admitted to hospital with pyonephrosis caused by fungus balls. Fluconazole-resistant Candida sake was grown. Treatment with external drainage of the renal pelvis and intravenous and local administration of caspofungin resulted in relief of the obstruction. Eradication of the infection was achieved by surgical removal of the ureter with all stents and construction of a cysto-pyelostomy.

We report a rare case of ectopic ureter accompanied by a giant ureteral stone and pyonephrosis. A 19-year-old Japanese woman consulted our hospital due to low-grade fever and pain in the left flank. The patient had seeping urinary incontinence since childhood. Ultrasonography demonstrated left dysplastic lumbar kidney with hydronephrosis and plain kidney-ureter-bladder film showed a left giant ureteral stone. The left kidney showed no excretion of contrast medium on drip infusion pyelography. After further examination, a diagnosis of left simple ectopic ureter emptying into the vagina was made. Percutaneous nephrostomy penetrating the major psoas muscle was carried out for intractable pyonephrosis, followed by left nephroureterectomy and lithectomy. These procedures resulted in improvement in the patient's symptoms.
