ABSTRACT

Objective To explore the clinical efficacy of modified single-portlaparoscopic radical prostatec-tomy(LRP) by atransperitoneal or extraperitoneal approach, and the impact of either approach on immune function in patients with prostate neoplasms. Methods The clinical data on 39 patients who had undergoneextraperitoneal LRP(group A) and 20 patients who had receivedtranperitoneal LRP (group B) in our department from January 2012 to December 2015 were retrospectivelyanalyzed. The prostate neoplasms were preoperatively diagnosed as cancer by ultrasound, CT or MRI, and pathological examinations. The clinical stage was T1-T2c , N0M0 in all patients.The efficacy was assessed by surgical duration, intraoperative blood loss, timeto intestinal function recovery, and post-operative hospital stay in both groups. The indicators for immune function including prostate specific antigen (TPSA and FPSA), immunoglobulin (IgG, IgA, lgM, C3, and C4) and T lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) in patientswith prostate neoplasms before and after surgery were detected. Results 59 patients were operat-ed successfully, without converting to open approach. The mean surgical duration, blood loss, time to intestinal function recovery, and postoperative hospital stay were (133.8 ± 68.6) min, (75.6 ± 51.3) mL, (2.2 ± 0.7) days, and (14.7 ± 3.6) days in group A, while (159.4 ± 78.1) min, (102.2 ± 70.8) mL, (2.9 ± 1.1) days, and (15.2 ± 4.1) days in group B. There were significant differences between the two groups (P0.05). Average postoperative follow-up was 15 months (range 3-36) in 36 patients. No recurrence or metastasis was found in all the patients by imaging studies,and no long-term complications were found. Conclusions Extraperitoneal LRP, as compared with tranperitoneal LRP, has clearer vision, fewer effects on abdominal organs, shorter surgical duration, less blood loss, faster postoperative recovery, and better protection of immune function. It is worth popularizing clin-ically.

ABSTRACT

OBJECTIVE: Complication incidence of urinary fistula which frequently occurs following renal transplantation is 3%-10%. Thus, poor processing may cause loss of transplanted kidney. This study was designed to retrospectively analyze urinary fistula following renal transplantation and to summarize the processing experience. METHODS: A total of 27 out of 1 203 patients with urinary fistula following renal transplantation (16 males and female 11 and mean age of 43 years) were collected from Guangzhou General Hospital of Guangzhou Military Command of Chinese PLA from December 2000 to March 2009. Totally, 26 patients accepted donor kidney from corpse, and 1 from living body. All patients were treated with expectant treatment (n=17) including inserting 18Fr Foley catheter alone and draining from the native drainage channel of operative site (n=12) and inserting a ureteral stent (single-J) by cystoscope retrograde approach and inserting 18Fr Foley catheter into the bladder (n=5); exploring operation (n=10) including anastomosing ureter and bladder and placing ureteral stent (n=5) and anastomosing ureter and ureter of recipient and placing ureteral stent (n=5); pedicled omentum grafts to cover and surround stoma after suturing (n=6). RESULTS: Only 1 case was failed because kidney vain was injured in the second operation and the kidney was resected. Another 26 cases were cured. Within the 3 month to 7 years follow-up, the urinary fistulas did not relapse, no stegnosis or hydronephrosis, no urinary tract infection and renal function were normal. CONCLUSION: Rapid diagnosis and treatment for urinary fistulas after renal transplantation is imperative. First mostly patients may be cured by expectant treatment. If not then perform exploratory operation. Using peclicled omentum grafts to cover and surround stoma after suturing for complex urinary fistulas can raise achievement ratio of operation.

ABSTRACT

Objective To summarize the success of congenital penile curvature. Methods 401 cases of con-genital penile curvature,whose average age is 2. 5 years ,ranging from 1 year to 26 years old. Of all cases ,383 patients who have both hypespadias and penile cun, ature, only 18 patients are congenital penile curvatures. 295 paitents are slight curvature,85 patients are moderate curvature and 21 patients are severe curvature. Curvature correction was per-formed on a case-by-case basis by solution fibric trabs of ventrial urethra and surrounding,skin de-gloving, ff necessa-ry,dorsal plication,and confirmed by Gittes test. Results . Curvature correction was possible by mobilization of ure-thra after penile degloviag,only a few need dorsal plieation. Followup for 6 months to 2 years,396 patients are success at once. The others after a second surgery had 100% success. Conclusions Solution fibrie trabs of ventrial urethra and surrounding, skin de-gloving, if necessary,dorsal plication ,is the first choice to repair of the congenital penile cur-vature and have good results.

ABSTRACT

Objective To determine whether an increased number of transrectal biopsy cores improves the accuracy of biopsy Gleason score. Methods This study reviewed a total of 86 patients who were diagnosed as prostate cancer by transrectal needle biopsy and subsequently underwent radical prostatectomy (RP) without neoadjuvant therapy.The rate of grading concordance between biopsy and RP specimens was analyzed by dividing these patients into 2 groups according to the biopsy cores:group A,46 patients who underwent transrectai biopsy sampling of 6 cores,and group B,40 patients who underwent biopsy sampling of 13 cores. Results The concordance between prostate biopsy and radical prostatectomy Gleason score was 65.0%and 34.8% for 13 core and 6 core biopsy,respectirely (P<0.05).Furthermore,these findings tended to be more prominent as the biopsy Gleason score was lower.Multivariate analysis identified the number of biopsy cores and percent of positive biopsy cores as independent predictors of accurate Gleason grading regardless of other parameters examined in this study. Conclusion Extended needle biopsy may increases the accuracy of biopsy Gleason score for assessing final prostate cancer grade.

ABSTRACT

Objective To evaluate the efficacy and safety of the InVance bulbourethral sling for stress urinary incontinence in male patients.Methods Five male patients with incontinence after prostatectomy were treated with the perineal sling(InVance).The patients aged from 62 to 76 years(mean,67 years),and the history of the incontinence ranged from 2 to 6 years(average 4 years).Four of the cases were due to TURP,and one radical prostatectomy.All the cases had been failed to respond to conservative therapies.Before the procedures,urodynamic examination showed a mean abdominal leak point pressures(ALPP)at 25.5 cm H2O(20-32.5 cm H2O).Under spinal anesthesia,a 3-to 5-cm vertical incision was made between the scrotum and the anus with the patients at the lithotomy position to expose the right and left ischiopubic branches.We put the three screws with its sutures on each bone and fixed the sling.A cough test was performed systematically and ALPP was set over 60 cm H2O.Results The operation time was 50-85 min(mean,60 min)and intraoperative blood loss was 20-50 ml(average 30 ml).The catheter was removed at day 5 and none of the patients had urination difficulty.The cases were followed up for 6 to 24 months(mean,12.6 months),during which urodynamic examination showed an ALPP at 65 cm H2O(55-70 cm H2O).Among the patients,the 4 who had received TURP were cured,and the other one undergone radical prostatectomy was improved.Conclusions InVance bulbourethral sling is suitable for mild-to-middle urinary incontinence after prostatectomy.
