In Memoriam: Dr. Oliver Schlarp, F.E.B.U.
Dr. Oliver Schlarp

On Sunday August 12, our good friend and colleague Dr. Oliver Schlarp, Urologist at the Krankenhaus Korneuburg in Austria, passed away.

Oliver was born on April 6, 1973 in Vienna and studied medicine at Vienna University. He graduated with a degree in medicine in 1997 and joined the staff in Korneuburg in 1998.  He quickly proved himself to be a skilled surgeon with a strong scientific interest and excellent people skills.

Oliver is an example to us all.  He was both an idealist as well as a realist. He contributed significantly over the years to the development of the department at Korneuburg, both through his input in discussions and by setting an example through his personal behavior.

Dr. Schlarp was, from the early days, involved in the development of the ProACT system to treat male incontinence. He co-authored two manuscripts on ProACT (published in the British Journal of Urology and most recently in European Urology). He was well known for this work, both in and outside of Austria.

Oliver Schlarp leaves a void that can not be filled by others. He will be remembered by all as an excellent urologist, a charismatic person and a valued friend.

Oliver leaves behind his wife Azita Schlarp Ahmadzadeh.

Two Articles Support Safety of ACT  

Two recent articles in Pelviperineology, "a multidisciplinary pelvic floor journal" shed light on two important aspects of the Adjustable Continence Therapy as used in female patients. Cadaver studies were carried out by an Australian/Italian team led by Dr. Helen O'Connell (University of Melbourne) and Dr. Ervin Kocjancic (Avogadro University, Udine).

Italy and Australia flags Cadaveric study of ACT Balloons and their impact on female sexual anatomy. O'Connell H. et.al. Pelviperineology 2007; 26, 53-56.

This study examines the extent of structural disruptions caused by insertion of the ACT balloons (using trocars and a u-channel sheath) and the possible impact of this device on the female sexual anatomy. Article concludes that insertion of the ACT trocar device in the location, depth and direction described in the article, did not damage the clitoris or its neurovascular supply.

Italy and Australia flags Anatomical basis for effective placement of adjustable continence therapy (ACT) balloons for the treatment of female stress urinary incontinence. Kocjancic E. et.al. Pelviperineology 2007; 26, 88-90.

This study examines various anatomical aspects related to successful balloon placement. Bilateral placement and expansion of the balloons at the posterolateral aspect of the vesico-urethral junction prevents downward, lateral and posterior displacement. The endo-pelvic fascia forms the roof of the space with the vaginal wall acting as a barrier to movement. The floor is composed by the urogenital membrane. Rapid balloon expansion was associated with rupture of the overlying endopelvic fascia highlighting the importance of the slow expansion recommended by the manufacturer.

Three articles were recently published on ProACT by investigators in Italy, France and Spain.

Italy Adjustable Continence Therapy for the treatment of male stress urinary incontinence: A single-centre study. Kocjancic E. et.al. Scand J Urol Nephrol. 2007; 41(4):324-8.

The article reports on the experience in 64 patients (post radical prostatectomy incontinence) who were implanted with ProACT.  At twelve months, 67% of patients were considered dry (0-1 safety pad per day) and a further 15% were improved. Quality of life improved from 31.7 at baseline to 71.1 at 12 months.  Nine patients required removal of the device which was easily achieved under local anesthesia. New balloons were implanted following endoscopic confirmation of urethral healing.

Spain flag Implante de balones parauretrales como tratamiento de la incontinencia urinaria masculine. Experiencie dl HospitalUniversitarion de la Paz. Cansino Alcaide JR et.al. Arch. Esp. Urol. 2007; 60, 6 (647-655), 200.

Article presents a retrospective review of series of 69 implanted patients with a mean follow-up of 22 months (3-48). 57% of patients no longer need to use pads, while 13% of patients use one safety pad. Stratified by degree of incontinence, 81% of patients with mild incontinence are dry as are 59% of those with moderate incontinence and 35% of those with severe incontinence (needing no protection whatsoever). In the latter group, if one adds the patients with one security pad, the dry rate would increase to 50%.

France flag Les ballonnets ajustables (ACT) périurétraux pour le traitement de l'incontinence de la femme (ACT periurethral adjustable balloons for treating female stress urinary incontinence) Le Normand L Pelv Perineol. 2007; Vol 2, 2 June  (198-202).

TThe author describes various SUI patients with complex clinical presentations and also discusses the value of ACT in the aforementioned groups. The article goes on to describe implant technique as well as postoperative care and management of complications. ACT is concluded to be a promising technique in complex or higher risk situations. It supplements the therapeutic arsenal in this population for whom there are few alternatives.

Congress Abstracts

ACT and ProACT at the ICS/WCE

During the recent annual meeting of the International Continence Society in Rotterdam, four abstracts were presented on the Adjustable Continence Therapy.

Italy Use of the Adjustable Continence Therapy for the treatment of recurrent female urodynamic stress urinary incontinence: Kocjancic E et.al.

The abstract reports on 49 female patients with a diagnosis of urodynamic stress incontinence and ISD. Mean follow-up of 40.1 months. I-QoL improved from 30 at baseline (N=49) to 93 at 48 months (N=23). Pad usage decreased from 5.4 at baseline (N=49) to 0.5 at 48 months (N=23). 81.3% of patients were either completely dry or significantly improved. Complications were minor and easily managed.

ItalyImplantation of ProACT System under local anesthesia in patients with post-radical prostatectomy stress urinary incontinence: a feasibility pilot study: Gregori A et.al.

Pilot study in 6 patients with SUI after radical prostatectomy. Procedure was performed under TRUS guidance with only local anesthesia.  Procedure is feasible and well tolerated. Potential advantages are the possibility to treat patients who are unfit to receive general anesthesia due to co-morbidities and possible cost reductions.

ItalyUse of the Adjustable Continence Therapy (ACT) treatment in pediatrics with neurogenic disorder: Kocjancic et.al.

Abstract describes experience with 4 male and 2 female incontinent patients (pediatric abstracts: average age of 10.8, range 7-16) evaluated for 18 months. Causes of incontinence included post myelomeningocele, post-spinal cord hemhorrage, bladder extrophy and epispadia. Despite the surgical challenges in this group (illustrated by the longer average operative time of 66 minutes). The outcomes were encouraging. At baseline 3 patients were wearing an average of 7 pads with two patients completely incontinent, of the totally incontinent patients one was wearing only 3 pads a day and the other remained unchanged. At last follow-up, 3 patients were dry, with one patient requiring anticholinergics, one patient requiring one pad per day and one patient requiring injection of a bulking agent in her stoma.

ItalyPredictive factors for successful outcomes following implantation of volume adjusted balloons: Kocjancic et.al.

Abstract reports on evaluation of ideal balloon placement in both male and female patients and provides suggestions for patient selection. Investigators found that patients could also achieve continence with asymmetrical balloon placement. Male patients who had undergone external beam radiation had a significantly lower success rate than those that did not have this treatment (57% vs. 77% required less than one pad per day).

During the recent annual meeting of the World Congress of Endourology and SWL in Cancun, Mexico, one abstract was presented on ProACT.

New ZealandProACT does not Impair Urinary Flow Rate: Gilling et.al.

In an abstract presented at the World Congress of Endourology (October 30-November 3, Cancun), Peter Gilling (Tauranga, New Zealand) and his team presented data on 37 patients with an average follow-up of 49 months. The flow rate (baseline 16.8 ml/s) was not significantly affected at 3 (15.6 ml/s), 6 (14ml/s) and 12 (18.1 ml/s) months.

At 24 months (N=27) the pad free rate was 66% and the proportion of patients requiring one pad or less per day was 84.8%.

The authors conclude that there is no discernable reduction in urinary flow following placement of ProACT balloons suggesting that simple obstruction is not the (only) mechanism.

ICS Members Looking for Artificial Sphincter Alternative

On Thursday August 23 during the plenary session at the annual meeting of the International Continence Society, an interesting point-counterpoint discussion took place. "Post radical prostatectomy incontinence; the artificial urinary sphincter is the first treatment option."  After listening to two experts present each side of the argument, the audience voted by applauding. A large majority of the audience clearly did not agree with this position and felt that less invasive and less costly options (such as ProACT) should be explored before considering the Artificial Urinary Sphincter.

ACT and ProACT Users Come Together in Rotterdam and Berlin
NetherlandsThe Dutch user group met during the ICS in Rotterdam. Guest speakers were Dr. Andrea Gregori (Milan) speaking about ProACT implantation using Transrectal Ultrasound (instead of the traditional fluoroscopy guidance) as well as implanting ProACT under local anesthesia. The other guest speaker was Dr. Ervin Kocjancic (Udine) who discussed his experience with ACT in pediatric neurogenic patients, as well as addressing various questions on the use of ACT in female patients.

Germany and AustriaSeveral weeks later, 14 German and Austrian physicians met during the Annual Meeting of the Deutsche Gesellschaft für Urologie in Berlin. ProACT presenters at this meeting were Dr. Wilhelm Hübner (Vienna), who analyzed the spectrum of treatments available for the patient with post radical prostatectomy incontinence and Dr. Christian Hampel (Mainz), who discussed his experience in 92 implanted patients. Dr. Stephan Madersbacher (Vienna) discussed the results with ACT in more than 40 complex patients, and Prof. Burckhard von Heyden (Bad Friedrichshall) reviewed using ACT in 11 patients and also discussed aspects of patient selection. After the meeting several of the participants stayed behind to ask questions and discuss individual patient cases.

Alert! Important Safety Information

ACT® Brief Summary of Safety Information for Physicians

Product Technical manual must be reviewed prior to use for detailed disclosure.

Indications: The ACT system is indicated for use in the correction of stress urinary incontinence in females.

Contraindications: Contraindications include active systemic or urinary tract infections, pregnancy, unmanageable detrusor instability, reduced bladder compliance, pretreatment urge incontinence symptoms refractory to medication, residual volume greater than 100 ml after voiding, pelvic-region radiotherapy within 6 months of ACT system implantation, bladder cancer or bladder stones, bleeding disorders.

Warnings/Precautions/Adverse Events: The ACT device is intended for single use only. Do not re-sterilize. Resterilization could result in mechanical failure of the device and place the patient at undue risk. Placement of the ACT device must be performed by a physician. If X-ray is used, adequate attention must be given to the potential radiation exposure. Perforation of the bladder, urethra or vagina during dilation of the tissue from the labia to the bladder neck should be avoided. Do not use excessive force to advance or withdraw the device if resistance is encountered. Do not attempt to place or introduce the device without the supplied push wire. Do not place the device in a location where the patient may have problems with urinary retention or erosion. Do not place the device immediately adjacent to the urethral mucosa. This could result in balloon erosion or migration. Do not place the device in a location where there are surgical staples, steel suture or other artifacts from previous interventions. Device wear and/or puncture may result. Do not inflate the balloon with more than 8.0 ml of isotonic contrast solution. Use the correct mixture of sterile water and contrast media to provide an isotonic contrast solution for inflation of the ACT balloons. Do not use the implantation instruments without prior cleaning and steam sterilization. The ACT system should only be used by a physician who has completed appropriate training. Patients should be pre-medicated with an antibiotic to reduce the possibility of postoperative infection. If ACT balloon failure, or bladder, urethra or vaginal wall perforation occur, do not implant and ACT device on the affected side for at least sixty days. An effective procedure calls for two devices to be placed. If the patient becomes pregnant after ACT implantation, the primary physician must closely monitor the patient for any adverse effects associated with the device during pregnancy. Failure of the device may result if the ACT device is handled with any sharp instruments or laid against an abrasive material. ACT balloons should be filled with saline instead of isotonic contrast solution if the patient is allergic to contrast media. It is advisable to use the same type of contrast media as used during the original filling of the balloons when performing a post surgical adjustment. The patient should refrain from heavy lifting and exercise for 3 to 4 weeks postoperatively and refrain from intercourse for one month. Advise the patient to contact the surgeon immediately if bleeding or other problems occur. Potential adverse events include, but are not limited to tissue perforation (tear), device migration, tissue erosion/infection at the implant site, device failure, non-response to treatment, post-operative urgency, frequency or retention.
