Description
DRAINAGE CATHETER FOR URINARY NEO-BLADDERS
DESCRIPTION
TECHNICAL FIELD : SURGERY/UROLOGY
BACKGROUND ART
It is very common in the clinical practice the need to remove the urinary bladder in males,women,children,secondary to tumours,infections,neurologic abnormalities,or malformations.
Bladder trauma are also very frequent after a car crash,a working accident or other,and may require a cistectomy.
The reconstruction of a new urinary bladder is common in the urologic practice utilizing different segments of the intestine or of the stomach.
Two foundamental types of urinary neo-bladders allow the patient to achieve the urinary continence: the orthotopic neo-bladders where the patient voids through the penis, helping himself with the contraction of the abdominal musculature,and as in the normal condition the continence is achieved with the natural sfincter ;
the neo-bladders with stoma in which the neo-bladder fashioned with a continence mechanism,is in communication with the abdominal wall,and the patient catheterizes himself through a stoma to void regularly.
The common post-operatory catheters utilized for the drainage of the neo-bladders are the same bladder catheters in use from many years to drain the natural bladder in several conditions(elderly condition,surgery of the
5 prostate,endoscopic or partial surgery of the bladder,etc...) .The construction of a a bladder(urethral) catheter is usually made with different materials ( Latex Rubber,Polivinile,Poliurethane,Co-Polimer,Silicone Rubber, etc..) in different shapes and dimensions, has a large
Q diffusion all over the world and do not shows particular, technical difficulties.The balloon that anchors the catheter is made of the same rubber-elastic material in different sizes and volumes,depending from the finalities,and can be inflated o deflated through a continent valve inserted
"7 tangential to the funnel of the catheter;the balloon can be fused to the catheter or simply sticked on it,depending on the technique.
The tip of a bladder catheter is very short, beeng about 3 cm.
Q Using the intestine in reconstructing the bladder,the intestinal mucosa is responsible of the frequent obstructions of the catheter by producing mucous secretions and mucous clots,with the risk of dangerous passive overdistensions of the neo-bladder just recently Q accomplished.The nurse personnel and the doctors must frequently wash the neo-bladders through the catheter along the two weeks of post-operatory period.
This is more and more important thinking that is impossible to leave a continuous washing flow through the catheter in Q the post-operatory period,becouse a sudden and inadvertent obstructions not ::apidly recognized by the medical and nursing staff, could determine a dangerous overdistension of the new fashioned bladder with possible rupture. Moreover, when a portion of the stomach has been utilized
I *] in reconstructing the bladder,a particular surgical procedure suitable for chidren,there is a production of Chloridric acid,digestive enzymes and mucous from the mucosa of the portion of the stomach utilized in the reconstruction. 2 τhe medical therapy cannot stop adequately the secretion of Chloridric acid that is sometimes responsible of severe bleedings from the mucosa(gastric) of the neo- bladders, often complained for a few months after the
neo-bladder procedure. 3 DISCLOSURE OF INVENTION
The use of a specific drainage catheter for neo- bladders that I invented,is indicated both for the orthotopic neo-bladders and the neo-bladders with stoma, either accomplished with the intestine or with the stomach.
Λ Λ Moreover,the specific catheter I invented for neo-bladders can be utilized to prevent the mucous obstruction when an enlargement cistoplasty of the natural bladder is performed with a segment of intestine. This is obtained by the particular lenght of the tip, 5 anci for a different positioning of the balloon from the apex of the catheter.
Moreover,the catheter is characterized by several holes along the tip of the catheter that allow a big surface of drainage;the catheter material warrants its
1 fo resistance to the mucous incrustation and to the acid secretions of the stomach.
Finally,for the specific design and the characteristics it is possible to wash and irrigate through the neo-bladder with extreme efficacy,removing the eventual mucous clots.
1 " The Bladder catheters commonly in use have the tip, very short -measured from the distal end of the balloon to the apex of the catheter.
The catheter I invented,specially projected for urinary neo-bladders has a very long functioning tip, Q containing several holes to drain the urine and the mucous secretions produced by the mucosa of the intestine utilized in reconstructing the new bladder. The holes along the common bladder catheters are usually only three.The catheter I invented has several holes Q regularly placed along the two opposite sides of the tip in alternate fashion with the same diameter and distance one to each other side to side.
A bigger hole is positioned at the apex of the tip and it is the bigger one. 0 τhe specific,technical characteristic of the catheter I invented are the following ones:
1) The catheter can be made with the Latex Rubber Hydrogel coated or with Silicone Rubber materials,both fused and shaped. If the catheter is made in Latex Rubber it is necessary, in order to improve its resistance to the incrustations and to improve a constant lubrification of the urethra for all the time in which the catheter is in place, that the catheter will be Hydrogel coated,a technique that in 2 commonly in use on other catheters from the market.
If the catheter is made in silicone rubber,the catheter maintain more consistance and rigidity without loosing too much the elasticity,and also the silicone make the catheter resistant to the incrustations from mucous and from the erosion by the acid secretions from the stomach when utilized,allowing to leave the catheter in place for a long time.
2) The following measurements are referred to a catheter of
22 French,the most commonly used in the clinical urologic « practice.
"French" is a common measurement unit for bladder catheters and follows this equation: 1 mm.= 0,39 inches = 3 French.
A) The total leng t of the catheter is 52 cm. ;partial measurements of this total are the following ones: 5 "the portion from the funnel(included) to the base of the balloon is 35 cm. The funnel is 4,5 cm.
B) From the base of the balloon to the distal end of the balloon the lenght is 3 cm if the balloon is fused to the catheter.Depending on the technical modality of (5 construction,the balloon can also be sticked to the catheter covering it for 3,5 cm. while the catheter maintains the same total lenght reported above of 52 cm.
C) From the distal end of the balloon to the tip of the catheter the lenght is 14 cm. *7 3) ^e tip of the catheter is close at the apex,rounded acutely and 1 hole of 10 mm.X 4 mm. is placed posteriorly and superiorly to the apex.
4) The number of the holes placed along the surface of the tip (from the distal end of the balloon to the apex of the o catheter measuring 14 cm. is divided as follow:
D) A total of 11 holes, 10 out of them measure 8 mm.X 3 mm.; 1 hole measures 10 mm.X 4 mm.
E) - 5 holes are positioned on the left side of the catheter. 9 - 5 holes are positioned on the right side of the catheter,in alternate fashion to the contralateral.
- 1 hole is positioned posteriorly and superiorly at the apex of the catheter and measures 10 mm.X 4 mm.
F) The distance between the opposite holes, from side to 0 side of the catheter measures 1,6 cm.
5) The balloon has a volume of 30 cc.,is made of the same material of the catheter and can be fused or sticked on it. (see point B) .
6) The catheter has an external diameter(section) of 7,3 mm. ( equal to 22 French,a conventional measurement unit of the catheters) for the whole lenght of the catheter excluding the funnel portion. G) The catheter has at its internal two co-axial channels: the first channel is 3,7 mm. in diameter(except for the funnel portion),is shaped as a tunnel,and put in communication the two extremities of the catheter: the holes along the tip of the catheter with the funnel portion and then the outside.
The second channel is positioned in the thickness of the wall of the catheter just peripheral and co-axial to the first channel and measures 0,7 mm. in diameter. This thin channel put in communication a continent valve, with the balloon.
The continent valve is implanted for fusion tangential to the catheter and placed parallel to the funnel,with the balloon.
The continent valve measures 6,5 cm.and generally for the 22 French catheters is about 1 cm. in the external diameter,depending from the type of valve already existing taken from the market.
7) The first channel at the funnel end measures 7,5 mm. and can be connected to the common syringes for catheters of 60 ml. or 100 ml. funnel shaped in use to wash the bladder. 6 8) τhe catheter material (see point 1 of the description) is mixed with Barium Solphate in such a percentage that can make the catheter visible inside the neo-bladder with a conventional X-Rays equipment in the post-operatory period. The catheter of my invention,even with large variations in
^ sizes from the child to the adult (10 Fr.;12 Fr.;l4 Fr.;16 Fr.;18 Fr. ;20.Fr. ;22 Fr.;24 Fr. where "Fr." means "French" a common measurement unit of the catheters) , can maintain the same configuration and the same shape following this equation 1 mm.= 0,39 inches = 3 French.
38 So,a new generation of post-operative catheters develops in different sizes for the adequate drainage of continent neo- bladders either orthotopic or with stoma.
