To introduce the technique of anatomical retroperitoneoscopic retroperitoneal lymph node dissection （ARRPLND） was performed in 12 consecutive patients with a clinical stage I nonseminomatous germ-cell tumor （NSGCT） between February 2008 and October 2010. All procedures were performed using a modified template nerve-sparing approach. The retroperitoneal space was adequately expanded using double gasbags. After the retroperitoneal fat was cleared, two relatively bloodless planes were entered consecutively to expose the lymph node and permit dissection. Dissection proceeded first in the plane between the anterior renal fascia and posterior peritoneum, and secondly in the avascular plane between the posterior renal fascia and transversalis fascia. The proximal spermatic vein was clipped at the initial stage. En bloc resection of the lymph tissue and fat between the anterior renal fascia and posterior renal fascia were performed. Three patients （25%） had pathologic stage IIA disease and received adjuvant chemotherapy. No recurrence was observed during follow-up ranging from 26 to 58months. The median operative time was 205min （range： 165-430min） and median estimated blood loss was 320ml （range： 100-1200ml）. There were two intraoperative complications （Clavien grade II） and one open conversion due to perforation of the peritoneum. Postoperative complications （Clavien I） developed in three patients. Normal antegrade ejaculation recovered by 1 month following the operation. Our preliminary results indicate that ARRPLND is technically feasible and associated with satisfactory clinical outcomes for clinical stage I NSGCT. Further studies are necessary to evaluate this technique.

OBJECTIVE:To explore the feasibility and safety of retroperitoneoscopic nephroureterectomy for kidney tuberculosis.;METHODS:Forty-eight retroperitoneoscopic nephroureterectomies and thirty-five nephroureterectomies for kidney tuberculosis procedures were performed from June 2008 to December 2014. The patients consisted of 53 males and 30 females with a mean age of 36 years (range: 26-51 years). The patients' data were reviewed and analyzed.;RESULTS:The retroperitoneoscopic nephroureterectomy procedures were completed successfully in 48 cases with no conversions to open surgery. The mean operating time was 170 minutes (range: 121-258 minutes), the mean blood loss was 110 ml (range: 70-250 ml), and the mean hospital stay was 5.70 days (range: 5-14 days); these were all much less than nephroureterectomy procedures ( 0.05). Seventy-five patients were followed up, and the average follow-up time was 12.5 months (range: 6-20 months). All the patients recovered without any lesions remaining.;CONCLUSIONS:The results of this study indicate that retroperitoneoscopic nephroureterectomy is a feasible, safe, effective, and less invasive treatment modality for treating renal tuberculosis.

Minimally invasive techniques in benign and malignant adrenal tumors

World Journal of Clinical Cases 2022年第35期10卷 12812-12821页

Minimally invasive adrenalectomy has become the main treatment modality for most adrenal lesions.Both laparoscopic transabdominal and retroperitoneoscopic approaches are safe and feasible options,each with respective advantages,including better surgical outcomes,fewer complications,and faster recovery over open adrenalectomy.While open surgery remains a valid modality in treatment of adrenocortical cancer in the presence of some findings such as invasion,robotic platforms,and minimally invasive surgery have gained popularity as technology continues to evolve.Organ preservation during adrenalectomy is feasible in some conditions to prevent adrenal insufficiency.Ablative technologies are increasingly utilized in benign and malignant tumors,including the adrenal gland,with various outcomes.A multidisciplinary team,an experienced surgeon,and a highvolume center are recommended for any surgical approaches and management of adrenal lesions.This review article evaluated recent findings and current evidence on minimally invasive adrenalectomy.

Clinical Experience in the Treatment of Nephroptosis Using Retroperitoneal Laparoscopic Nephropexy

Open Journal of Urology 2014年第6期4卷 78-81页

作者： Ruojing Wei Affiliated Hospital of Hebei University Baoding China

Background: Retroperitoneal laparoscopic nephropexy has been applied to nephroptosis. We investigate the approach and treatment effect of retroperitoneal laparoscopic nephropexy. Methods:?From May 1990 to October 2013, 45 patients with nephroptosis treated in our hospital were retrospectively analyzed. Among them, 25 patients underwent nephropexy (open surgery group), the other 20 patients underwent?retroperitoneal laparoscopic nephropexy (laparoscopic surgery group). In open surgery group,?there were 24 females and 1 male, aged 20 - 35 years. In laparoscopic surgery group, there were 19 females and 1 male, aged 20 - 35 years.?All of them with?nephroptosis of the right kidney were combined with lower back pain or hematuria and underwent intravenous pyelography (IVP) and color?ultrasound?in?orthostatic and supine position for a specific diagnosis. In open surgery group, patients underwent open surgery. Their kidneys were?fully dissociated,?then, the upper and?middle pole of the dorsal kidney was?sutured?with?lumbar fascia?for two stitches for fixation respectively. While in?laparoscopic surgery group,?kidneys were fully dissociated in Gerota’s fascia during laparoscopic surgery, and?the upper pole of the dorsal kidney was sutured?with the?lumbar fascia for?two?stitches using a?2-0 absorbable suture. They were all in the supine position for a week after surgery.?The?body mass index (BMI), operation time, bleeding?amount,?postoperative hospital stay,?wound complication rate and other indicators were compared between two groups. Results:?BMI in open surgery group was 16.77 ± 0.80 kg/m2, BMI in?laparoscopic surgery group was 16.73 ± 0.78 kg/m2, P > 0.05 showed no statistical difference;the operation time in open surgery group was 70.96 ± 10.61 min, that in laparoscopic surgery group was 34.65 ± 4.87 min, P?< 0.001?showed highly statistical significance;the bleeding amount in open surgery group was 20.65 ± 6.48 ml, that in laparoscopic surgery group was 4.85 ± 1.63ml, P < 0.001 showed highly statistical significance;th
