OBJECTIVES: Patients with polycystic kidney disease are candidates for kidney transplant. We report the results of our single center study of 250 first transplant recipients with polycystic kidney disease (autosomal dominant [64%], medullary cystic [16%], autosomal recessive [6%], and nonspecified [14%]). MATERIALS AND METHODS: Patient groups were divided and analyzed according to the origin of the graft (deceased donor or living donor). We also analyzed demographic data of donors and recipients, waiting time, duration of dialysis, transfusion, nephrectomy, hospitalization, morbidities, and graft and patient survival...

PURPOSE: This study evaluates the frequency of ureteral repair and its management in patients with a history of gynaecologic surgery. MATERIALS AND METHODS: After retrospective review of the medical records of all major gynaecologic operations performed over a six-year period (2004-2010), 17 cases of ureteral repair were identified. The indication and the type of gynaecological surgery, the anatomic site, the indication, the type of ureteral repair and the associated morbidity were analyzed...

A Piepsz, R Sixt, I Gordon
The aim of this work is to present to the reader the practical experience of three clinicians having actively participated to the publication of the guidelines on renography in children. The present publication should be considered as a practical guide. We have underlined good practice, obvious errors to avoid, common pitfalls which might be overlooked, some items for which more than one reasonable solution exists and finally a few controversial points, for which there is still no agreement and no solid evidence to resolve these issues...

Renal transplantation is the treatment of choice for most patients with end-stage renal disease. However, in spite of continuous progress in surgical techniques and immunosuppressive therapy, a wide variety of vascular and nonvascular complications can arise postoperatively. Vascular complications include transplant renal artery stenosis, arteriovenous fistulas or intrarenal pseudoaneurysms following renal transplant biopsy, extrarenal pseudoaneurysms, and graft thrombosis. Nonvascular complications include urologic complications (eg, ureteral obstruction, urine leak) and perigraft fluid collections (eg, lymphocele, abscess, hematoma, urinoma)...

To study the surgical treatment and outcome of hydronephrosis secondary to pelviureteric junction obstruction (PUJS) that is so massive that the renal pelvis crosses over the vertebral column [mega-hydronephrosis (MH)]. Of the 40 cases of PUJS we treated over the past 5 years, 6 cases had MH secondary to PUJS (MH-PUJS) in 6 renal units and were reviewed. Incidence of MH was 15.0%. All had Anderson-Hynes dismembered pyeloplasty to treat obstructive renal pattern on technetium-99m diethylenetriaminepentaacetic acid (DTPA) scans in five and gait disturbance due to MH in one...

PURPOSE: We evaluated the durability of endourological intervention for ureteropelvic junction obstruction and established guidelines for postoperative surveillance. MATERIALS AND METHODS: Since 1989, 150 patients have undergone endourological intervention for ureteropelvic junction obstruction, of whom 127 (53 men and 74 women) 13 to 79 years old (mean age 40.4) underwent postoperative evaluation at our center. These 127 patients are the study group reported. Endourological management consisted of hot wire balloon endopyelotomy in 25 patients, percutaneous endopyelotomy in 67 and ureteroscopic laser endopyelotomy in 35...

A. Any significant deterioration in graft function should be investigated using the appropriate diagnostic tools and, if possible, therapeutic interventions should be initiated. The usual causes of a decline in glomerular filtration rate after the first year include transplant-specific causes such as chronic allograft nephropathy, acute rejection episodes, chronic calcineurin inhibitor nephrotoxicity, transplant renal artery stenosis and ureteric obstruction, as well as immunodeficiency-related causes and non-transplant-related causes, such as recurrent or de novo renal diseases and bacterial infections...

OBJECTIVE: To evaluate whether intrarenal surgery for branched calculi remains valid in the light of current new techniques, e.g. percutaneous nephrolithotomy and extracorporeal shockwave lithotripsy. PATIENTS AND METHODS: Between January 1978 and October 1984, 44 patients (24 male and 20 female, mean age 42.5 years, range 14-66) underwent complex surgery for large stones, requiring opening of the renal pelvis and a transparenchymal approach to the calices; 47 renal units were operated in 49 procedures...

The recognition of high retreatment rates and lower success rates after SWL monotherapy in certain situations led us to explore a new endourologic strategy including retrograde intrarenal surgery (RIRS). Examples of situations in which RIRS + SWL is appropriate are coexistence of stones and coagulopathy, stones associated with intrarenal stenosis, concomitant renal and ureteral stones, renal anomalies, and failed SWL. Lithotripter-specific guidelines for the adjunctive use of RIRS may be appropriate.

The pathogenesis of reflux nephropathy and morbidity is discussed first, then chances of spontaneous maturation and risks for scarring are compared with resulting guidelines for conservative and operative treatment. A list of indications is proposed regarding grade of reflux, age, essential diagnostic parameters (VC, cystoscopy, IVP), history and other clinical aspects. Over and above this, an "ephedrine-test" developed at Erlangen in 1976 is described with regard to possible adrenergic treatment of primary reflux...

A sixteen day old infant developed candiduria after surgery on a single functioning, hydronephrotic kidney with ureteropelvic junction stenosis. Masses of candida albicans caused obstruction of the ureter with acute anuria. Endoscopic relief of the obstruction together with aggressive antifungal therapy led to irradication of the fungal infection. This case history emphasizes the fact that candida infection in early childhood should be evaluated carefully. Unfortunately no guidelines are yet available for the indications and the preferred mode of treatment, and length of therapy of infantile renal candidiasis...

Acquired infundibular stenosis is an unusual complication resulting in pancalyceal obstruction. We have cared for 6 patients with acquired infundibular stenosis not associated with tuberculosis. All patients had urinary diversion with ileal conduits for a minimum of eleven years and documented ileal-ureteral reflux and chronic urinary tract infections. The clinical, radiographic, and pathologic characteristics of this syndrome are described and therapeutic guidelines suggested.
