ABSTRACT

Objective To analyze the safety and efficacy of autogenous femoral lateral iliotibial fascia(autologous fascia lata) in the treatment of female stress incontinence.Methods The clinical data of 7 female patients with stress incontinence admitted from January 2016 to June 2017 were retrospectively analyzed.The mean age was 58.2 years (range 45-72 years).The mean disease duration was 10.7 years (range 5-21 years).The mean Body mass index (BMI) was 24.1 kg/m2 (range 20.3-31.4 kg/m2).7 patients had severe subjective scores according to clinical symptoms.The average score of urinary incontinence questionnaire-simple form (ICIQ-SF) of international urinary incontinence advisory committee was 14.3 ± 1.1,the score of incontinence-quality of life (I-QOL) was 24.3 ± 4.8,respectively.During general anesthesia,the patient was placed in a half-recumbent position with the right leg straight down and the left leg bent over.The position of patella as well as the iliotibial band of the lateral femoral muscles were marked on the body surface.The iliotibial fascia of the lateral femoral muscle was exposed through a transverse incision 4-6 cm perpendicular to the iliotibial fascia of the lateral femoral muscle.The fascia of the lateral iliac tibial fascia of the lateral vastus with a width of 1.5 to 2.0 cm and a length of 12 to 14 cm was cut.The fascia was immersed in physiological saline and sutured with two 2-0 CT1PDS absorbable sutures or 2-0 vascular sutures at both ends of the fascia for 3 consecutive needles to form a sling.Then the urethral catheter was placed in the position of lithotomy,and then urethral suprapubic suspension was performed using autologous fascia through bilateral paravaginal incisions.The duration of surgery,intraoperative blood loss,intraoperative complications,postoperative catheter indwelling time,the length of hospital stay and postoperative complications were recorded.The situation of urinary incontinence as well as life quality before and after surgery were compared respectively.Results The operation was successfully performed.The mean operative time was 117.6 min(range 95-140 min).The mean intraoperative blood loss was 70.3 ml (range 50-90 ml).No complication was observed during the operation.The mean postoperative indwelling catheterization was 5.8 days (range 5-7 days).The mean postoperative hospital stay was 6.3 days (range 5-8 days).All 7 patients were cured after surgery,2 patients experienced urinary retention after removal of the catheter.The mean follow-up time was 18.2 months(range 13-24 months).No urinary incontinence or complications was observed postoperatively in all cases.Patient ICIQ-SF urinary incontinence questionnaire summary score and quality of life score of I-QOL questionnaire of 1 year post operation were 0.6 ± 0.5 and 96.1 ± 4.3,which were significantly improved compared with that before surgery(P < 0.01).Conclusion It is safe to use autologous femoral lateral muscle iliotibial fascia in the middle segment of urethra suspension for the treatment of female stress incontinence,and the curative effect is affirmative through one-year observation.

ABSTRACT

Objective To understand the effect of circumcision in reducing high-risk human papilloma virus (HPV) infection in male adults. Methods One hundred and twenty-eight married adults with phimosis who underwent circumcision enrolled in the case group and high-risk HPV of urethral discharge specimens were detected before and 2 years after operation. A total of 128 cases of phimosis without circumcision were recruited in the control group. High-risk HPV infection rates were compared between the two groups. Results The highrisk HPV infection rates in the two groups were comparable at baseline. In the circumcision group, high-risk HPV infection rate was 27. 3% preoperative and it significantly decreased to 12.5% two years after operation( x2 =8. 839 ,P =0. 005). In the control group,high risk HPV infection rate was 28. 1% at baseline and it was 25.0%two years later, with no significant difference (x2 =0.320,P = 0.671).Conclusion Circumcision can significantly reduce high-risk HPV infection. Promoting circumcision actively in our country may have an important role in preventing high-risk HPV infection.

ABSTRACT

Objective To present our initial experience in laparoscopic radical prostatectomy performed through an umbilical incision using a home-made multichannel port. Methods From August 2009 to March 2010, we performed single-port laparoscopic radical prostatectomy in 11 patients with localized prostate cancer. A home-made multichannel port was inserted extraperitoneally through a 3-cm umbilical incision. The single port extraperitoneal procedures included obturator fossa lymphadenectomy, radical prostatectomy and urethro-vesical anastomosis, while the urethro-vesical anastomosis was performed by a slip-knot running suture technique. Data were collected and analyzed prospectively. Results All cases were completed successfully, without conversion to a standard laparoscopic approach or open surgery except adding an additional port in one case. The average operative time was 256 minutes (range195-315), and the mean blood loss was 90 ml (range 20- 180), without any blood transfusion. The postoperative hospital stay was 15.4 days (range13- 24), and the Foley catheter was removed 12 days after surgery. No intraoperative complications occurred. One patient developed a vesico-rethralanastomosis leakage, 2 had lymphatic leakage and 1 had urinary tract infection,all of the cases were managed successfully with conservative treatment. Histopathological results showed negative surgical margine and negative lymph node dissection. All patients had no biochemical relapse after an average follow-up of 7 months. Conclusions Single-port laparoscopic radical prosta tectomy is feasible, cosmetic and minimally invasive with a low complication rate and good short-term outcome. Additional investigation is needed to evaluate the long-term safety and oncologic adequacy of this new approach.

ABSTRACT

Objective To study the feasibility and safety of performing nephrectomy together with the removal of complicated inferior vena cava tumor thrombus under profound hypothermia and arrested circulation. Methods After made the median thoraco-abdominal incision, the exploration of the abdominal organs was done. The right kidney, inferior vena cava and renal pedicle were well exposed then. After the whole body heparinization, cannulas were put into ascending aorta, superior vena cava, aortic root and right superior pulmonary vein. The body temperature was reduced to 20℃ with cardiopulmonary bypass unit and the extracorporeal circulation was stopped then. Cut open the inferior vena cava at vena renalis dextra ingress and the F16 urinary catheter was inserted into atrum dextra through inferior vena cava and inflated. The tumor thrombus was pulled out and the right kidney was removed. The inferior vena cava incision was sutured to close and the extracorporeal circulation was resumed and patient was re-warmed.Results The operation time was 330 min and the extracorporeal circulation time was 90 min, while the profound hypothermia with circulatory arrest time was 20 min. The estimated blood loss during operation was 400 ml and 6 unit red cells and 600 ml blood plasm were transfused. The patient was awaked 2.5 h after the operation, food intake resumed 4 days after operation and the patient was discharged on day 10 post-operatively. After 6 months'follow-up, there were no local recurrence and metastasis occurred. Conclusion The technique of profound hypothermia and circulation arrest could improve the safety and efficacy in the treatment of renal cell carcinoma with suprahepatic (level Ⅲ) caval tumor thrombus.

ABSTRACT

Objective To compare the therapeutic effects of 3 operative options with selective high level ligation of spermatic veins, transinguinal canal and renovated Potomo's laparoscopic manage-ment of varicocele. Methods From January 1990 to November 2006, 1075 primary varicocele above grade Ⅱ patients accepted the operations, of them, 685 patients had follow up data and were recruited into this study. These patients were divided into 3 groups according to the operative methods:group A (n=369) was treated with open selective high level ligation of spermatic veins, group B (n=218) was treated with open transinguinal canal operation, and group C (n=98) was treated by renovated Polo-mo's laparoscopic management of varicocele. The complications of the 3 operative methods were com-pared, such as recurrence rate, testicular atrophy rate, scrotal edema rate and semen analysis. The therapeutic effects of these 3 methods were evaluated. Results The recurrence rates of the 3 groups were 3.3%, 7.3% and 5.1%, respectively. Group A had significantly lower recurrence rate than group B, P<0.05. The testicular atrophy rates of 3 groups were 0.5%, 17.9% and 9.2%, respec-tively. There were significant differences among the 3 groups (P<0.05). The scrotal edema rates of the 3 groups were 1.4%, 17.4% and 16.3%, respectively. Group B and C had higher risk of scrotal edema than group A, P<0.05. For patients with ages younger than 30, the improved semen quality rate in group A was higher than in group B and C. The improved semen quality rate in each group of patients younger than 30 was higher than patients with age over 30. Conclusion The open selective high level ligation of spermatic veins is the best choice in the treatment for patients with primary sper-matic varicocele.

ABSTRACT

<p><b>OBJECTIVE</b>To report the surgical techniques and results of an 8-year follow-up study of 42 patients with a modified orthotopic ileal neobladder restoring normal anatomical relationship.</p><p><b>METHODS</b>Total cystoprostatectomy was performed extraperitoneally. A 45 - 50 cm segment of the ileal loop was isolated, detubularized, and reconfigured into an "M"-shape to form a pouch. Bilateral ureters were implanted by inserting 1 cm distal segment into the pouch. The bottom of pouch was opened and anastomosed with the urethra.</p><p><b>RESULTS</b>Forty-two patients were followed up for 6 to 96 months,90.5% of whom were continent in the daytime, and 85.7% at night. Two patients had a difficulty in urination. The average volume of the pouch was (361 +/- 48) ml at 12 months postoperation. Urodynamic examination showed the average peak voiding pressure was (86.8 +/- 21.4) cm H(2)O. The average maximum flow rate (Qmax) was (18.4 +/- 6.1) ml/s. No remarkable ureter reflux and obstruction were found. No patient was detected to have urethral carcinoma.</p><p><b>CONCLUSIONS</b>Extraperitoneal cystectomy can avoid the tumor contamination of the abdomen and intestinal interference of the operative field. The ureter-inserting implantation technique is a simple anti-reflux anastomosis method with less ureter stenosis rate. Isolating the neobladder and ureters from the peritoneal cavity can reduce the postoperative complications, such as adhesive ileus, internal hernia, and urine leakage into the peritoneal cavity. The neobladder is similar to the original bladder in position, volume, shape and anti-reflux ureter connection.</p>

ABSTRACT

Objective To present the initial experience and results of the laparoscopic radical cystectomy (LRC) with orthotopic ileal neobladder. Methods Fifteen patients (14 men and 1 women) with invasive bladder carcinoma underwent LRC with orthotopic ileal neobladder.The mean age was 59.5 years(range,39 to 71 years).The LRC with orthotopic ileal neobladder consists of 3 major steps,namely laparoscopic cystectomy,extracorporeal formation of ileal pouch and laparoscopic urethra-pouch anastomosis.With 5 trocars,the surgeon conducted the procedure through the 2 ports on the left side,and the assistants did so on the right side and hold the laparoscope.The bilateral pelvic lymphadenectomy were performed first.The ureters were dissected just outside the bladder.The radical cystoprostatectomy was performed for the male patients.The total bladder, uterus and appendage were removed for the female patient.A 4 to 5 cm median incision in lower abdomen was made to remove the surgical specimens and construct the ileal pouch.A 50 cm ileal loop was taken from the abdominal cavity,isolated,detubularized and reconfigured into “M” shaped pouch with running suture.The anti-refluxing ureter implantation was performed by inserting the 1 cm of ureter into the pouch and suturing them.For the first 4 cases,the urethra-neobaldder anastomosis was completed through the abdominal incision;while for the other 11 cases,the anastomosis was done under the laparoscope. Results The mean duration of surgery was 5 to 10 h with a mean of 6.5 h;the blood loss was 200 to 1000 ml with a mean of 387 ml.During a follow-up of 1 to 11 months,all patients were alive and asymptomatic with normal upper tracts and had no evidence of local recurrence or metastasis.4 to 6 weeks after surgery,all the patients with orthotopic ileal bladder had complete daytime continence,and nocturnal continence was achieved with 2 to 3 times voiding at night. Conclusions This procedure combines the advantages of minimally invasive laparoscopy with the speediness of open surgery.The laparoscopic cystoprostactomy has a magnified clear vision,which makes meticulous manipulation possible,and reduces bleeding,sphincter injury and nerve bundle injury.Shorter time of intestine exposure during the procedure is good for recovery of intestinal function and for reducing postoperative intestinal adhesion.External construction of ileal pouch shortens operation time remarkably.Ileal segment has long and mobile mesentery,thereby can be easily taken out through a small abdomen incision and anastomosed with urethra stump without tension,so it is more suitable for construction of a pouch.

ABSTRACT

Objective To evaluate the outcomes of M-shaped orthotopic ileal neobladder. Methods A total of 42 male patients with malignant bladder tumors underwent M-shaped orthotopic ileal neobladder after extraperitoneal total cystoprostatectomy.A segment of 45 to 50cm ileal loop was isolated,detubularized,and reconfigured in “M”- shape to form a pouch.Bilateral ureters were reimplanted by means of inserting the 1 cm distal segment into the pouch.The bottom of pouch was opened and anastomosed with the urethra. Results The 42 patients were followed up for 12 to 96 months with a mean of 44 months.38 cases(90.5%) were well continent during daytime,and 36 cases(85.7%) were continent at night.The volume of the pouch was (361?48)ml at 12 months postoperatively. Urodynamic examination showed that the peak voiding pressure was (86.8?21.4)cm H 2O(1 cm H 2O=0.098 kPa).The maximum flow rate (Q max ) was(18.4?6.1)ml/s.No remarkable ureter reflux and obstruction were found.No patient was detected to develop recurrent urethral carcinoma. Conclusions Extraperitoneal cystectomy can prevent the abdomen from tumor contamination and protect the operative field from intestine interference.The ureter-inserting reimplantation technique is a simple anti-reflux anastomosis with lower rate of ureteral stenosis.Isolating the neobladder and ureters from the peritoneal cavity can reduce the postoperative complications of adhesive ileus,internal hernia,and urine leakage to peritoneal cavity.The neobladder is similar to original bladder in position,volume,shape,and anti-reflux of ureter connection.

ABSTRACT

AIM: To investigate serum vascular endothelial growth factor (VEGF) level in patients with bladder transitional cell carcinoma(BTCC) and its clinical significance. METHODS: ELISA method was used to examine the serum VEGF level in 42 cases of bladder transitional cell carcinoma and in 10 cases of normal people as control. The change of VEGF in blood of the pre-operation and post-operation patients with BTCC was also compared. RESULTS: The VEGF level in blood of the patients was higher than that of the normal people, in spite of pre-operation, post-chemotherapy, and post-operation, but VEGF level decreased obviously after chemotherapy or operation. In addition, the plasma VEGF level was related to the grade and invasion of tumor. CONCLUSION: Detecting serum VEGF level can help us to assess the change of tumor and therapeutic effect.
