    ABSTRACT: In patients with autosomal dominant polycystic kidney disease (ADPKD), laparoscopic cyst decortication (LCD) has been proposed as a means to relieve chronic cyst-related pain. We present our 7-year experience with LCD for ADPKD with regard to pain relief, hypertension, and renal function. Between August 1994 and February 2001, 29 ADPKD patients with chronic pain (N=29), hypertension (N=21), and renal insufficiency (N=10) underwent 35 LCD procedures. Every detectable cyst within 2 mm of the renal surface was treated. Pain relief was assessed using a pain analog scale; relative pain relief (RPR) equaled (preoperative pain score) - (postoperative pain score)/(preoperative pain score). Hypertension was evaluated using the antihypertensive therapeutic index (ATI): [(dose of blood pressure medication 1/max dose 1) + (dose med 2/max dose 2) + etc.] x 10. Renal function was assessed using the Cockcroft and Gault formula for creatinine clearance. The mean operating room time was 4.9 hours (range 2.6-6.6 hours) with no conversions to open surgery. An average of 220 cysts (range 4-692) were treated per patient. The mean follow-up was 32.3 months (range 6-72 months). The RPR was 58%, 47%, and 63% at 12, 24, and 36 months, respectively. At 12, 24, and 36 months, 73%, 52%, and 81% of patients, respectively, noted >50% improvement in their pain compared with the preoperative situation. Five patients became normotensive, and patients improved their ATI by an average of 49% (range 11%-93%). However, six patients had worsening hypertension, with an ATI increase averaging 53% (range 11%-122%), and one patient who was not hypertensive preoperatively has since developed hypertension. The creatinine clearance changed +4%, +7%, and -2% at 12, 24, and 36 months, respectively. Only one patient had a >20% increase in creatinine clearance. The only patients with a >20% decrease in creatinine clearance were those who had a creatinine clearance <30 mg/dL preoperatively (average decrease 34% [range 20%-51%]). For ADPKD patients with debilitating pain, extensive LCD can provide durable relief. In the majority of patients with pain and hypertension, a marked improvement in blood pressure also occurs. Cyst decortication was not associated with worsening renal function; indeed, renal function remained largely unchanged over the 3-year follow-up period.

    ABSTRACT: The authors report a case of intractable autosomal dominant polycystic kidney disease-related pain associated with normal renal function, treated with renal denervation. Renal denervation was performed via a thoracoscopic approach. The good medium-term result suggests that thoracoscopic sympatho-splanchnicectomy would be an attractive procedure for pain management in autosomal polycystic kidney disease.

    ABSTRACT: Laparoscopic nephrectomy in patients with autosomal dominant polycystic kidney disease (ADPKD) is technically challenging. We describe our technique and present our experience with a transperitoneal hand-assisted laparoscopic (HAL) technique using a standard vacuum curettage system to reduce the size of the kidneys thereby facilitating nephrectomy. A retrospective review was completed of 10 consecutive patients undergoing bilateral HAL nephrectomy between March 2002 and October 2004 using the following technique. A hand port is positioned through a 6-7 cm periumbilical incision and port sites are placed at the midclavicular line (12 mm) and anterior axillary line (5 mm) on the side of the initial nephrectomy. After the renal vessels are divided and the kidney is completely mobilized a 12 mm curette is inserted through the medial port site. The Berkeley VC-10 Vacuum Curettage System (ACMI, Southborough, MA) is used to morcellate and aspirate the kidney providing a significant decrease in the overall size and allowing easy extraction through the midline incision. The procedure is repeated for the contralateral side. All 10 patients underwent successful bilateral HAL nephrectomy with a mean operative time of 194 minutes. The average length of stay was 4.7 days. Patients with renal allografts had stable function at the time of discharge. The average size of the kidneys removed was 717 g and average length was 19 cm. All patients did well postoperatively with complete resolution of their presenting symptoms. In patients with symptomatic ADPKD, bilateral HAL nephrectomy using the vacuum curettage system to minimize the size of the kidneys is fast, safe and effective.
