    „Laparoscopic implantation of temporary electrodes for bladder stimulation in dogs", Neurourology and Urodynamics 15: 149-155, 1996
    Five female mongrel dogs were used in an acute animal experiment. Under general anesthesia two monopolar wire electrodes armed with needles on either side were implanted into the bladder wall, the leads of both electrodes were then pulled through the abdominal wall. Filling of the bladder and intravesical pressure measurement were achieved through a suprapublic percutaneous cystostomy. Electrostimulation was carried out using the XEJ-2 experimental electroejaculator (biphasic pulses, pulse width 2.5 msec, approximately 70 mAmp, 50 Hz). The pressure changes within the bladder following electrostimulation were recorded, the effect of stimulation was observed endoscopically. Electrostimulation of the bladder wall resulted in micturition in all cases, showing an initial pressure peak at the commencement of electrostimulation followed by a decrease after onset of evacuation. We believe that laparoscopic implantation of temporary wire electrodes followed by percutaneous electrostimulation may open up new possibilities for bladder rehabilitation as well as for diagnostic investigations into the contractile capabilities of the bladder.

    „Experience in renal autotransplantation: analysis of a clinical series",
    British Journal of Urology 77, 518-523, 1996
    OBJECTIVE: To determine the benefit of renal autotransplantation in selected patients with either renovascular lesions, renal or urothelial carcinomas or other disorders of the urinary collecting system. PATIENTS AND METHODS: Between 1977 and 1994, 12 patients underwent renal autotransplantation, six involving renovascular hypertension, two involving tumours of the renal parenchyma, two with urothelial tumours and two with long ureteric stenoses. Pre-operative renal function was normal in six patients and impaired in five. One patient was on haemodialysis. Five patients had a solitary kidney and four patients had functionally solitary kidneys. The follow-up period ranged from 1 to 93 months (mean 34.9). RESULTS: Post-operatively, six patients had normal kidney function (serum creatinine < or = 12 mg/L), five patients had impaired renal function (creatinine content < or = 26 mg/L) and one patient was on haemodialysis due to arterial graft thrombosis. Serum creatinine levels improved in four patients and were stable in another four. Renal function deteriorated in three patients and one patient required a graft-nephrectomy. Immediate post-operative complications included arterial thrombosis in one patient, perirenal haematoma in two, pulmonary oedema in one and severe intra-operative bradycardia requiring a transient cardiac pacemaker in one. CONCLUSION: Renal autotransplantation represents an effective alternative treatment with good long-term results for selected patients with long ureteric lesions and renovascular disorders. It is also an effective method for patients with urological malignancies, especially those with solitary kidneys where the maintenance of renal function is of major concern.

     „Intravesical electromotive drug administration (EMDA) for the treatment of non-infectious chronic cystitis", 
     Eur.Urol., 30, Supp.2,208 (765 A), Abstr., 1996
     Seventeen patients with non-infectious chronic cystitis (NICC) (9 with interstitial cystitis, 6 patients with radiation cystitis, 1 with chemocystitis and 1 with lupoid cystitis) were treated with electromotive administration of intravesical lidocaine and dexamethasone followed by hydrodistension of the bladder. Complete resolution of symptoms for an average of 7.5 months was observed in 11 patients (65%), partial improvement in 4 (23.5%). In this series no complications occurred. Electromotive drug administration (EMDA) and cystodistension were well tolerated by all patients. The treatment was performed on an outpatient basis, thus reducing therapeutic costs. The results presented demonstrate that the combination of EMDA and bladder hydrodistension is an effective first-line treatment for NICC patients.
