The retrocaval ureter is a rare congenital anomaly. The extrinsic compression may be responsible for obstruction and pain symptoms. The laparoscopic approach has been used with good results and less morbidity than the open surgery. Herein we describe a case of retrocaval ureter treated with LESS. To our knowledge, this represents the second such case reported in the literature, and the first without using any special devices, such as, single port or bended instruments. PRESENTATION Female, 23 years, complaining of right low back pain for a long time and recurrent urinary tract infection. Renal ultrasound demonstrated right-sided hydronephrosis and intravenous urography suggested the presence of retrocaval ureter. DTPA renal scintigraphy confirms delay in the elimination of contrast through the right kidney. A laparoendoscopic single-site repair was planned. The patient was placed in rightside-up modified flank position. A semicircular intra-umbilical incision was made and the conventional trocars (one 10 mm and two 5 mm) were inserted through the same incision on different points of the aponeurosis. The colon was dissected medially and the proximal ureter lateral to the vena cava was identified and dissected. An extra corporeal repair with Vycril 2-0 was used to facilitate the ureteral dissection and the anastomosis. A segment of ureter was ressected due to the tortuosity. Two 4-0 Vycril sutures were used to perform a running anastomosis. An ureteral stent was placed after the posterior layer on an antegrade fashion. A suction drain was left through the umbilicus. RESULTS The total operative time was 145 min. The blood loss was minimal. The patient was discharged on the third postoperative day and resumed total activity about 10 days after surgery. The double J was removed within 4 weeks. DISCUSSION Albeit technically challenging, LESS repair for retrocaval ureter might represent a feasible new treatment option for this rare anatomic anomaly. Special devices could help on the procedure, however they are not essencials.

Inroduction Acquired bladder diverticula are herniations of the bladder mucosa through detrusor muscle. Due to the ineffective emptying of the bladder diverticulum, urine accumulation may lead to urinary tract infection, stone disease, and lower urinary tract malignancy in the diverticulum (1). The symptomatic bladder diverticula may require surgical treatment. Surgical approaches include open operation via an extravesical or a transvesical approach for large diverticula or endoscopically with transurethral fulguration for small diverticula (2). Herein, we present a video of a Laparoscopic Bladder Diverticulectomy for recurrent urinary tract infection, aided by concurrent cystoscopy. Materials and methods Female patient, 37 years old, complaining of recurrent urinary tract infection for three years. A bladder diverticulum was found on ultrasonography. Cystoscopy revealed a posterior right-side diverticulum next to the ipsilateral ureteral ostium. A laparoscopic bladder diverticulectomy with the aid of intraoperative cystoscopy was proposed. Surgical Technique Under general anesthesia, the patient was placed in lithotomy and Trendelenburg position. An umbilical incision was used for pneumoperitoneum creation and insertion of a 10mm trocar. Three other 5mm trocars were inserted at positions equidistant between the navel and the pubis, and between the umbilicus and the iliac crests bilaterally. Concomitant cystoscopy was performed for location of the diverticulum by transillumination and help to identify the diverticular neck. The diverticulum was dissected both sharply and bluntly until the whole diverticulum was freed. After completion the ressection, a catheter was inserted in the right ureter near the diverticulum to assess inadvertent lesions. The mouth of the diverticulum was closed by 2-0 double-layered absorbable running suture and a suction drain was placed through a lateral 5mm port. RESULTS The surgery was uneventful. The operative time was 120 minutes with minimal blood loss. There was no postoperative leakage, the drain was removed after 24 hours and the patient discharged. The indwelling catheter was removed after 7 days and the patient progresses without voiding complaints or new infectious episodes in a follow-up of 10 months. Conclusions Laparoscopic diverticulectomy is technically feasible and safe. The concomitant use of cystoscopy facilitates the identification and location of the diverticulum, thereby minimizing dissection of the bladder and decreasing operative time. Cystoscopy may also be useful in the delineation of margins in cases of neoplasia within the diverticulum.

Introduction Guillain-Barre syndrome is an acute neuropathy that rarely compromises bladder function. Conservative management including clean intermittent catheterization and pharmacotherapy is the primary approach for hypocompliant contracted bladder. Surgical treatment may be used in refractory cases to improve bladder compliance and capacity in order to protect the upper urinary tract. We describe a case of pure laparoscopic augmentation ileocystoplasty in a patient affected by Guillain-Barre syndrome. Presentation A 15-year-old female, complaining of voiding dysfunction, recurrent urinary tract infection and worsening renal function for three months. A previous history of Guillain-Barre syndrome on childhood was related. A voiding cystourethrography showed a pine-cone bladder with moderate post-void residual urine. The urodynamic demonstrated a hypocompliant bladder and small bladder capacity (190mL) with high detrusor pressure (54 cmH2O). Nonsurgical treatments were attempted, however unsuccessfully. The patient was placed in the exaggerated Trendelenburg position. A four-port transperitoneal technique was used. A segment of ileum approximately 15-20cm was selected and divided with its pedicle. The ileal anastomosis and creation of ileal U-shaped plate were performed laparoscopically, without staplers. Bladder mobilization and longidutinal cystotomy were performed. Enterovesical anastomosis was done with continuous running suture. A suprapubic cystostomy was placed through a 5mm trocar. Results The total operative time was 335 min. The blood loss was minimal. The patient developed ileus in the early days, diet acceptance after the fourth day and was discharged on the seventh postoperative day. The urethral catheter was removed after 2 weeks. At 6-month follow-up, a cystogram showed a significant improvement in bladder capacity. The patient adhered well to clean intermittent self-catheterization and there was no report for febrile infections or worsening of renal function. We did not experience any complication related to the intestinal anastomosis fully prepared intracorporeally. Conclusions Albeit technically challenging, pure laparoscopic enterocystoplasty was feasible and safe. Preparing the enteral anastomosis and the pouch intracoporeally may prolong surgical time and contribute to postoperative ileus. Surgical staplers can assist in the procedure, however they are not essential.
Pure laparoscopic radical heminephrectomy for a large renal-cell carcinoma in a horseshoe kidney
(International Braz J Urol, 2013-07) Rebouças, Rafael Batista; Monteiro, Rodrigo C.; Souza, Thiago N.; Barbosa, Paulyana F.; Pereira, George G.; Britto, Cesar Araujo
Introduction Horseshoe Kidneys are the most common renal fusion anomaly. When surgery is contemplated for renal-cell carcinoma in such kidneys, aberrant vasculature and isthmusectomy are the major issues to consider. We describe a case of a pure laparoscopic radical heminephrectomy with hand-sewn management of the isthmus for a 11 cm tumour in a horseshoe kidney. Presentation A 47-year-old man complaining of palpable left flank mass for two months. Magnetic resonance of the abdomen revealed a 11 cm renal mass arising from the left moiety of an incidentally discovered horseshoe kidney. Preoperative CT angiography revealed a dominant anterior renal artery feeding the upper and midpole, with two other arteries feeding the lower pole and isthmus. The patient was placed in a modified flank position. A four-port transperitoneal technique was used, the colon was reflected. Renal pedicle was dissected and the renal arteries and renal vein were secured with polymer clips. The kidney was fully mobilized and a Satinsky clamp was placed on the isthmus for its division. A running 2-0 vicryl hand-sewn was used for parenchyma hemostasis. The specimen was extracted intact in a plastic bag through an inguinal incision. Results The operative time was 220 minutes, and the estimated blood loss was 200 mL. There were no immediate or delayed complications. The patient resumed oral intake on postoperative day 1 and was discharged on postoperative day 2. Pathologic examination of the specimen confirmed a 11 cm organ-confined chromophobe renal-cell carcinoma, with negative margins. Discussion Laparoscopic oncologic surgery in patients with horseshoe kidneys can be technically challenging. The presence of a large cancer in a horseshoe kidney should not preclude a purely laparoscopic approach. With the aid of a Satinsky clamp, the isthmus can be sharply divided and sutured in a fashion similar to the open technique. To our knowledge, this report represents the largest cancer (11 cm) removed laparoscopically in the context of a horseshoe kidney.
