ABSTRACT

<p><b>OBJECTIVE</b>To summarize the features and treatment of male infertility induced by autosomal dominant polycystic kidney disease (ADPKD), and compare the outcomes of intracytoplasmic sperm injection (ICSI) for infertile men with ADPKD and those with congenital bilateral absence of vas deferens (CBAVD).</p><p><b>METHODS</b>We retrospectively analyzed 21 cases of ADPKD-induced infertility, 15 treated by ICSI (group A), and another 164 cases of strictly matched CBAVD-induced infertility (group B). We compared the two groups in the couples' age, the number of ICSI oocytes, and the rates of fertilization, transferrable embryos, good embryos, embryos implanted, clinical pregnancy, biochemical pregnancy, early abortion, singleton and twins in the first cycle.</p><p><b>RESULTS</b>After 28 cycles of ICSI, 10 of the 15 ADPKD-induced infertility patients achieved clinical pregnancy, including 7 cases of live birth, 1 case of spontaneous abortion, and 2 cases of pregnancy maintenance. No significant differences were observed between groups A and B in the couples' age, the wives' BMI, or the numbers of ICSI oocytes and embryos transplanted (P >0.05), nor in the rates of ICSI fertilization (72.64% vs 76.17%), transferrable embryos (51.28% vs 63.24%), quality embryos (38.46% vs 49.83%), embryo implantation (17.64% vs 38.50%), abortion (0 vs 9.23%), singleton (50% vs 81.54%) and twins (50% vs 18.46%). However, the rates of clinical pregnancy (13.33% vs 42.68%, P = 0.023 <0.05) and biochemical pregnancy (13.33% vs 39.63%, P = 0.032 <0.05) were significantly lower in group A than in B.</p><p><b>CONCLUSION</b>ICSI is effective in the treatment of male infertility induced by either ADPKD or CBAVD, but the ADPKD cases have a lower success rate than the CBAVD cases in an individual cycle. The affected couples should be informed of the necessity of prenatal genetic diagnosis before embryo implantation and the inevitable vertical transmission of genetic problems to the offspring.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the safety and feasibility of testis-sparing surgery (TSS) in the treatment of testicular tumor.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data of 8 cases of benign testicular tumor treated by TSS in our hospital from October 2005 to March 2012.</p><p><b>RESULTS</b>The 8 patients, aged 18-67 (mean 45) years, were preoperatively diagnosed with benign testicular tumor and all underwent partial testis resection. Rapid intraoperative pathology showed the incisal margins to be negative. Postoperative pathological examination confirmed Sertoli cell tumor in 3 cases, adenomatoid tumor in another 3, and mature teratoma in the other 2. The patients were followed up for 6 months to 7 years (mean 4 years), which revealed no relapse and metastasis, nor significant differences from the baseline in the testosterone level, IIEF score, and routine semen parameters.</p><p><b>CONCLUSION</b>Testis-sparing surgery is one of the effective options for the management of benign testicular tumor, which can maximally preserve the testis tissue and protect the patient's sexual function.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effect of adjuvant hormonal therapy (AHT) immediately after radical surgery for high- risk organ-confined or locally advanced prostate cancer using the PSA-related biochemical relapse rate within 2 years after surgery.</p><p><b>METHODS</b>We retrospectively analyzed 62 cases of high-risk organ-confined or locally advanced prostate cancer. The patients were treated by laparoscopic radical prostatectomy or radical retropubic prostatectomy after MRI and ECT systemic bone imaging examination, which revealed no regional lymph node or bone metastasis. Thirty-two of the patients (group A) received AHT orally or subcutaneously from 2 weeks to 1 months after operation, and another 30 (group B) were left untreated. We followed up the patients for 2 years, measuring the serum PSA level every 3 months, performing ECT every 6 months, and recording the adverse reactions, medication dura- tion, and the patients'quality of life.</p><p><b>RESULTS</b>All the operations were successfully accomplished. The rate of 2-year biochemical relapse-free survival was 78.13% (25/32) in group A and 53.33% (16/30) in group B.</p><p><b>CONCLUSION</b>AHT immediately after radical surgery can improve the rate of biochemical relapse-free survival of the patients with high-risk organ-confined or locally advanced prostate cancer and check the progression and metastasis of the disease.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical characteristics and surgical treatment of penile Paget's disease.</p><p><b>METHODS</b>We retrospectively analyzed the treatment and follow-up data of 10 cases of penile Paget's disease surgically treated in Jiangsu Provincial Government Hospital and Jiangsu Provincial People's Hospital from 2008 to 2012.</p><p><b>RESULTS</b>All the 10 patients received expanded local resection of the lesion with reconstruction of the defects with scrotal skin flaps or free skin flaps from the thigh. All surgeries were successful and the postoperative course was uneventful with complete graft survival and no lymph node metastasis. IIEF scores obtained before and 1 -2 months after surgery showed no statistically significant differences in the penile erectile function (P = 0.229), sexual orgasm (P = 0.761), and sexual satisfaction (P = 0.801) of the patients.</p><p><b>CONCLUSION</b>When penile skin lesions suggest the possibility of Paget's disease, biopsy should be performed and surgery should follow as soon as possible. The ideal surgical option is expanded local resection of the lesion with reconstruction of the defects with scrotal skin flaps or free flaps according to the patient's specific conditions.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the safety and feasibility of glans-preserving surgery in the treatment of superficial penile cancer (SPCa).</p><p><b>METHODS</b>We retrospectively analyzed the clinical data of 21 cases of SPCa treated by glans-preserving surgery in our hospital from January of 2003 to March of 2010.</p><p><b>RESULTS</b>The study included 21 SPCa patients aged 36 to 57 (mean 46) years, with superficial lesions involving the glans penis, coronary sulcus or shaft skin. The tumors were staged and graded TaG1 in 6 cases, TaG2 in 5, TisG1 in 2, TisG2 in 4, T1G1 in 3, and T1G2 in 1. All the patients underwent glans-preserving surgery to preserve the normal appearance and functional integrity of the glans penis, and all returned to normal sexual activity 1 month after operation, with good sexual function and sexual satisfaction. Postoperative follow-up lasted 2 to 7 (mean 5) years, and 2 cases of recurrence in situ found at 6 and 9 months, respectively, which were successfully managed by a second glans-preserving surgery.</p><p><b>CONCLUSION</b>Glans-preserving surgery is an effective method for superficial penile cancer. With proper selection of the patients, this procedure is technically safe, maximally preserves the penile appearance, and least affects the patients' sexual satisfaction.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the technique and clinical outcomes of modified transperitoneal laparoscopic radical prostatectomy.</p><p><b>METHODS</b>A total of 105 patients received the operation with age ranging from 51 to 73 years from January 2008 to June 2010. Mean level of serum prostate specific antigen was 13.6 µg/L and mean prostatic volume was 45 ml. Pathological studies of biopsy confirmed the prostate carcinoma with Gleason score 6-8. Radionuclide bone scan revealed no metastasis. Based on previously retroperitoneal radical prostatectomy, modified technique was applied involving surgical approach, bladder neck dissection and vesicourethral anastomosis.</p><p><b>RESULTS</b>Mean operative time was 93 min (65 - 150 min). Intraoperative blood loss was 115 ml (50 - 400 ml). No complication of bowl injury occurred. Positive surgical margin was present in 24 patients. Normal continence were seen in 64 patients after catheter removed. Recovery of incontinence within 3 months was seen in 33 patients and 3 to 12 months in 5 patients respectively. Three patients with incontinence were still in the follow-up.</p><p><b>CONCLUSIONS</b>Transperitoneal laparoscopic radical prostatectomy provides large working space and clear anatomic exposure. Higher efficiency and lower complication rate are obtained through modified laparoscopic technique involving seminal vesicle isolation, bladder neck dissection and vesicourethral anastomosis.</p>

ABSTRACT

Objective To discuss the treatment of ureteropelvic junction obstruction by laparoscopic pyeloplasty. Methods A retrospective review of consecutive laparoscopic pyeloplasty in 102 patients between September 2001 and December 2007 was performed. The ureterpelvic junction was dissected and the obstruction portion was excised. Anastomosis was then performed through the ureter and the renal pelvis walls with a stent. Results The mean operating time was 120 min and the average blood loss was 80ml. No major complication occurred intraoperative. The drainage was removed in 3-10 days. The average hospital stay was 8.5 days. The stent was kept for 30-60 days. IVU and B ultrasound examination revealed that the hydronephrosis alleviated during the follow-up and no anastomosis stricture occurred. Conclusions Laparoscopic dismembered pyeloplasty could provide lower morbidity, shorter hospital stay, and faster convalescence. It could be an effective treatment for ureteropelvic junction obstruction.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the role of spermatic nerves in the regulation of spermatogenesis.</p><p><b>METHODS</b>Fifty-four mature SD male rats (350-375 g) were randomized into a sham operation group (SO) and three experiment groups, and the latter underwent bilateral surgical removal of the superior spermatic nerve (SSN) or/and the inferior spermatic nerve (ISN). The animals were killed 1 month and 2 months after the operation. HE stain was used to observe spermatogenesis. Transmission electron microscopy and terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) were employed to detect apoptosis.</p><p><b>RESULTS</b>Impaired spermatogenesis was observed 2 months after the operation, with only Sertoli cells and a few spermatogonia remaining in the regressed tubules in all the treatment groups. The abnormal tubules in the SSN, ISN and SSN + ISN denervated testes accounted for (13.25 +/- 2.03)%, (11.0 +/- 4.36)% and (34.17 +/- 3.78)% respectively. Chromosome condensation and fragmentation in the germ cells were observed under the electron transmission microscope in all the denervated testes. TUNEL showed the spermatogonia and Leydig cells to be apoptotic in all the denervated testes and the incidence of the apoptotic cells in the SSN + ISN denervated testes was significantly higher than in the SSN or ISN denervated ones.</p><p><b>CONCLUSION</b>Spermatic nerves play an important role in spermatogenesis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To detect the changes of the expression of Bax and Bcl-2 gene in the denervated testis, and to explore the possible mechanisms underlying the apoptosis of germ cells induced by testicular denervation at the genetic translation level.</p><p><b>METHODS</b>Eighteen mature SD rats (350-375 g) were equally divided into 3 groups: a sham operation group( SO) , a superior spermatic nerve group (SSN) and an inferior spermatic nerve group (ISN) , and the latter two received bilateral surgical removal of the superior spermatic nerve and the inferior spermatic nerve, respectively. The animals were killed I month after the operation. ISH SP-method was used to detect the expression of Bax and Bcl-2 protein.</p><p><b>RESULTS</b>Significant up-regulation of Bax protein was detected in both the treatment groups 1 month after surgery( P <0. 05) , and the level of Bcl-2 protein remained unchanged.</p><p><b>CONCLUSION</b>Bax gene is involved in the apoptosis of germ cells induced by testicular denervation.</p>
