ABSTRACT
<p><b>BACKGROUND</b>Retrocaval ureter is a rare congenital abnormality. Operative repair is always suggested in cases of significant functional obstruction. Laparoscopic procedures have been employed as the minimally invasive therapeutic option for retrocaval ureter. However, the laparoscopic techniques for retrocaval ureter might be technically challenging to some surgeons. The aim of this article was to present our experience and surgical techniques of pure transperitoneal laparoscopic pyelopyelostomy and ureteroureterostomy in nine patients with retrocaval ureter.</p><p><b>METHODS</b>A total of nine patients of retrocaval ureter underwent pure laparoscopic pyelopyelostomy or ureteroureterostomy. The operation was performed with the patients placed in the 70-degree lateral decubitus position via a three port transperitoneal approach with two 10-mm and one 5-mm ports. The distal part of the dilated renal pelvis was transected at the ureteropelvic junction and the ureter was relocated anterior to the inferior vena cava. The tension-free pyeloureteral or ureteroureteral anastomosis was completed with the intracorporal freehand suturing and in situ knot-tying techniques combined with interrupted and continuous fashion. A double J ureteral stent was inserted in an antegrade manner during laparoscopy. Intravenous urography or computerized tomography and renal ultrasonography were performed after 3 months postoperatively.</p><p><b>RESULTS</b>All operations were completed laparoscopically, and no open conversion was required. The mean operative time was 135 minutes (range, 70 - 250 minutes), with minimal blood loss (less than 60 ml). No intra-operative complications or significant bleeding occurred. All patients presented mild postoperative pain and quick convalescence. The symptoms disappeared and hydronephrosis decreased substantially after surgery.</p><p><b>CONCLUSIONS</b>Pure transperitoneal laparoscopic correction for retrocaval ureter was associated with an excellent outcome, minimal invasiveness and short hospital stay. It is technically feasible and reliable for retrocaval ureter treatment. Laparoscopic surgery could be the standard treatment for retrocaval ureter.</p>

<p><b>OBJECTIVE</b>To investigate the transvesical approach to the surgical treatment of seminal vesicle mass.</p><p><b>METHODS</b>Transvesical removal of seminal vesicle mass was performed for 5 patients aged 45-69 (mean 51) years. The clinical symptoms included those involving the lower urinary tract such as frequent micturition and urgency in 3 cases (1 accompanied with dyschezia), hematospermia in 1, and lower abdominal and perineal malaise in the other. Two masses were in the left side and the other 3 in the right, ranging from 3 to 10 cm (mean 5 cm) in size, detected by transrectal ultrasonography, CT, MRI or digital rectal examination. The mean course of disease was 9 (2-18) months.</p><p><b>RESULTS</b>All the 5 patients were treated successfully and uneventfully, with a mean operation time of 75 minutes, a mean blood loss of 140 ml and a mean hospital stay of 10 days. Pathological examinations revealed 2 cases of seminal vesicle cyst with infection, 1 cystadenoma, 1 phyllode tumor and 1 prostatic hyperplasia. A 3-72 months follow-up showed that all the patients were free of symptoms and had normal sexual function.</p><p><b>CONCLUSION</b>Transvesical removal of seminal vesicle mass, with small incisal opening, good visual field and easy operation, is an effective surgical procedure for seminal vesicle disease.</p>

<p><b>OBJECTIVE</b>To evaluate the feasibility and short-term clinical effect of transperitoneal laparoscopic modified retroperitoneal lymph node dissection (LmRPLND) in the management of clinical Stage I nonseminomatous germ cell testicular tumors.</p><p><b>METHODS</b>From October 2004 to July 2006, 7 patients aged 26-36 (mean 30) years underwent LmRPLND with modified unilateral template dissection for clinical Stage I nonseminomatous germ cell testicular tumors, which were 3.0 cm x 2.5 cm x 2.0 cm to 6.5 cm x 4.5 cm x 3.0 cm in size, 3 cases on the left and 4 on the right, all diagnosed by ultrasound, computerized tomography (CT) and chest X-ray and confirmed by biopsy following radical orchiectomy. Those with positive lymph nodes received 3 courses of chemotherapy.</p><p><b>RESULTS</b>Success was achieved in all the 7 cases, the operative time ranging from 120 to 210 min (mean 160 min), blood loss from 50 to 200 ml (mean 150 ml), and with no blood transfusion. The drainage tubes were removed 1-2 days after surgery. The mean postoperative hospital stay was 5.5 days. The follow-up lasted 6-32 (mean 14) months, which revealed normal erection and ejaculation in all the patients, but no major postoperative complications. Pathologically, lymph nodes were negative in 6 cases and positive (1/18) in 1. Normal results were obtained in HCG and AFP tests as well as in retroperitoneal ultrasound and chest X-ray examinations. The patient with positive lymph nodes was treated by adjuvant chemotherapy for 3 courses and found free of malignancy during a 6-month follow-up.</p><p><b>CONCLUSION</b>LmRPLND is a safe and minimally invasive treatment option for patients with clinical Stage I nonseminomatous germ cell testicular carcinoma. With fewer complications and faster recovery, it appears to be a desirable substitute for the open procedure.</p>

A large stone with 8.7 cm multiply 7.2 cm multiply 6.5 cm in size and 420 g in weight dropped down spontaneously from a 93-year-old man's scrotum, who had suffered from left intrascrotal mass and pain for more than 20 years. The component of the stone was magnesium ammonium phosphate. To the best of our knowledge, it is the largest intrascrotal calculus reported in the world. We hereby present the case and discuss the diagnosis and etiology of scrotal calculi.

OBJECTIVE: To identify the factors to transurethral resection of prostate (TURP) perioperative hypotension. METHODS: The study group included 130 patients undergoing TURP. The control group included 50 patients who had suprapubic prostatectomy. Absorption of irrigation fluid was measured by determining the serum gentamycin level. Blood loss of PURP patients was calculated as the product of the irrigation fluid volume and hemoglobin concentration (determined with a photometer) divided by the preopreative blood hemoglobin concentration. Body temperature was recorded using a rectal probe. Serum electrolytes were determined pre-and postop. RESULTS: The blood loss in study group (380.2+/-98.3)ml was significantly less than in the control group (460.1+/-52.5)ml, P<0.05. However, the incidence of hypotension was significantly higher than the control group 28%, 8%), P<0.01. Factors associated with TURP hypotension included volume of irrigation fluid absorption, blood loss, reduction in core temperature, decrease of serum sodium, operating time, prostate weight and volume and history of cardiovascular disease. After Logistic regression analysis, the most significant factors were excessive absorption of irrigation fluid and rapid central cooling. CONCLUSION: In our study TURP hypotension most closely correlated with volume of irrigation fluid absorbed and reduction in core temperature.
