1/9. Closure of mouth of bladder diverticulum via endoscopic transvesico-transurethral approach.We successfully treated bladder diverticula in two patients using the endoscopic transvesico-transurethral approach. The mouth of the diverticulum was closed in two layers under pneumobladder, using two percutaneous ports placed into the bladder as well as the urethral route. This operation was performed 2 to 3 months after the bladder outlet obstruction was relieved by transurethral resection or incision of the prostate. The patients were able to void with a minimum of residual urine. The endoscopic transvesico-transurethral approach provided satisfactory vision.- - - - - - - - - - ranking = 1keywords = diverticulum (Clic here for more details about this article) |
2/9. Bladder outlet obstruction after operation for ureterocele.Two patients with ureterocele-induced bladder outlet obstruction are presented. In each instance, a broad-based diverticulum had developed in the floor of the bladder as a result of the muscular defect created by a simple ureterocele in one patient and an ectopic ureterocele in the other. This bladder diverticulum produced secondary obstruction of the bladder outlet during the act of voiding. urinary diversion in one patient had been carried out because of bladder outlet obstruction and was being seriously considered in the other patient because of upper tract deterioration. After the correct diagnosis was established, reconstruction of the muscular defect eliminated the obstruction and reestablished satisfactory bladder function. urinary diversion was thus prevented in one patient and undiversion accomplished in another, when the true obstructing nature of the bladder diverticulum was established and correct therapy instituted.- - - - - - - - - - ranking = 0.6keywords = diverticulum (Clic here for more details about this article) |
3/9. Congenital bladder diverticulum: an unusual presentation with abdominal mass, urinary retention, and renal failure in a young adult.Computed tomographic (CT) evaluation of an abdominal mass diagnosed a huge 2-L congenital bladder diverticulum that caused urinary retention and ureteral compression leading to renal failure. The patient's renal failure resolved with decompression. His voiding dysfunction and retention resolved following diverticulectomy.- - - - - - - - - - ranking = 1keywords = diverticulum (Clic here for more details about this article) |
4/9. Intraoperative catheter management during laparoscopic excision of a giant bladder diverticulum.BACKGROUND: Massive bladder diverticula present a technical challenge to the laparoscopic surgeon. We describe a laparoscopic approach to transperitoneal diverticulectomy, using a specific catheter arrangement to allow excellent control of the various portions of the procedure. methods: A 49-year-old male with longstanding frequency was diagnosed with a 1000 cc bladder diverticulum and bladder neck outlet obstruction. Laparoscopic transperitoneal diverticulectomy was performed using a triple catheter arrangement: endoscopic placement of a Councill catheter in the diverticulum, fluoroscopic positioning of an occlusion balloon catheter in the renal pelvis, and placement of a Cope loop suprapubic tube. Additionally, a transurethral incision of the prostate was performed. RESULTS: The procedure was completed laparoscopically using a four port transperitoneal approach. During the procedure, the diverticulum could be filled and emptied as needed; the catheter across the diverticular neck facilitated subsequent closure of the bladder wall defect. The diverticulum was completely excised. The remaining defect in the bladder was then closed in 2 layers. The patient was discharged on postoperative day 3. CONCLUSION: Careful planning and arrangement of catheters in the bladder, ureter, and diverticulum facilitates laparoscopic transperitoneal diverticulectomy of even a very large volume diverticulum.- - - - - - - - - - ranking = 2keywords = diverticulum (Clic here for more details about this article) |
5/9. Laparoscopic bladder diverticulectomy for large bladder diveticulum: a case report.Bladder diverticula are herniations of the bladder mucosa through the bladder wall musculature. Acquired bladder diverticula are the result of outlet obstruction, mostly benign prostate enlargement, infections, or urethral stricture. Traditionally, bladder diverticulum was excised by the open method. However, the laparoscopic technique has been widely used to treat many urologic diseases, including bladder diverticulum. Laparoscopic diverticulectomy can be performed transperitoneally or extraperitoneally. We report our initial experience with laparoscopic transperitoneal diverticulectomy for a large bladder diverticulum caused by bladder outlet obstruction. The patient had satisfactory micturition and was discharged on the eighth postoperative day.- - - - - - - - - - ranking = 0.6keywords = diverticulum (Clic here for more details about this article) |
6/9. Inverted Y duplication of the ureter in association with ureterocele and bladder diverticulum.We report a case of inverted Y duplication of the ureter in association with an obstructing ectopic ureterocele and paraureteral diverticulum. Preoperative radiological studies demonstrated the ureterocele and diverticulum but they failed to show the duplex distal ureter. The duplicated section of ureter was excised and a Cohen reimplantation was performed. The presence of a large ureterocele obstructing the bladder neck, a diverticulum, failure of reflux into the ectopic segment and poor function of the affected kidney all contributed to the difficulties in establishing a preoperative diagnosis.- - - - - - - - - - ranking = 1.4keywords = diverticulum (Clic here for more details about this article) |
7/9. Hereditary autosomal dominant form of bladder diverticula in male patients.We report on 1 family in which 7 male patients had solitary bladder diverticulum. This family represents an autosomal dominant form of this disease by which only men are affected. Diverticula of the bladder can be classified as congenital (primary) or acquired (secondary). Vesical diverticula are uncommon in children and occur either primarily, when the vesical mucosa protrudes through a congenital defect in the bladder wall, or secondarily to bladder outflow obstruction. In adults the occurrence of multiloculated secondary diverticula is mainly due to subvesical obstruction. This seemingly autosomal dominant form of solitary diverticula in men was mostly associated with bladder outlet obstruction.- - - - - - - - - - ranking = 0.2keywords = diverticulum (Clic here for more details about this article) |
8/9. diverticulum of the urinary bladder.Vesical diverticulum predominates in males and is frequently associated with obstruction at or near the bladder neck. The obstruction may be due to benign prostatic hypertrophy, urethral stricture or, less often, carcinoma. diagnosis is made by intravenous or retrograde cystogram. Urinary stasis leads to recurrent infection and stone formation. While small diverticula may often be left alone, large ones should be surgically removed.- - - - - - - - - - ranking = 0.2keywords = diverticulum (Clic here for more details about this article) |
9/9. Sequential laparoscopic bladder diverticulectomy and transurethral resection of the prostate.The surgical treatment of prostatic obstruction associated with a clinically significant bladder diverticulum has classically combined open diverticulectomy with relief of the bladder outlet obstruction. This report demonstrates that this result may be efficiently achieved by performing transurethral surgery followed immediately by laparoscopic excision of the diverticulum. As assessed by a retrospective comparison with four open bladder diverticulectomies combined with transurethral resection of the prostate, laparoscopic diverticulectomy markedly reduces the postoperative and convalescence period. The overall financial saving that ensues may benefit both the patient and the healthcare system. Sequential laparoscopic bladder diverticulectomy and transurethral resection of the prostate illustrates the increasing possibilities of minimally invasive surgery.- - - - - - - - - - ranking = 0.4keywords = diverticulum (Clic here for more details about this article) |
